The “do it first, apologize later” will be the general principle with anything. It’s going to be hard and futile to prove even if they don’t do it through ToS first. Amazon has one of the largest corporate training sets out there:)
Yes I think you are right. Even a super ethical company can be taken over. There may be exceptions but it is more luck. I work for a SP500 that absolutely won't dont this and locks down prod access so a rogue staff can't do it. But if Larry or Zuck or Bezos buys them out, who knows.
Back in 2003 he was advocating for legalization of child sexual abuse material. In 2006 he said he was skeptical of the harm caused by “voluntary pedophilia”, a statement that presupposes that children can consent to sex with adults.
About communication with other humans he’s pretty much always wrong.
Imagine we’d had a better communicator who wasn’t a gross toe nail picking troll fronting free software? It shouldn’t matter. Only the ideas should matter . But the reality is different.
I’m still concerned about MS using the code I write on my laptop to train AI. Tinfoil hat wearing Linux users are starting to make a lot of sense to me.
It's been interesting the past year or so watching myself turn more and more into one of the tin-foil wearing linux users. I'm not sure how it happened, but self-hosting became more and more alluring and hyperfocusing on taking as much data as I can offline became worth spending entire weekends on.
I thought that’s more what the CoPilot change is really about - not your repo, but all the code CoPilot read while it is offering helpful completions, etc - so literally the code on your laptop. I cancelled my account.
Thank you for your service. We really need more "canaries in the mine" giving out early warnings of things that might not be evident on a first glance.
Any takes on what 2029 will look like? (related to this topic, ofc)
Pro tip: You could instead spend that money to spin up a forgejo instance for as little as $2 a month https://www.pikapods.com/apps#development (not affiliated, just a happy customer)
I did exactly that. Containerized it and Forgejo simply became a small instance part of the fleet. UI is much snappier then GitHub. And more importantly: zero outages.
An enterprise licence won't save you, Google, Microsoft, et al have happily been breaking copyright laws for years.
If the publishing industry can't win a case against the AI firms then you don't stand a chance when you finally find out they've been training on your private data the whole time.
They can tell you one thing and do the opposite and there's effectively nothing you can do about it. You'd be a fool to trust them.
Github's enterprise version "starts at" $21.99/seat, and requires you to "contact sales".
And I don't see any mention that that exempts you from being trained on. (Yes, the blog says you're still covered, but at that price I'd like to see a contract saying that)
Or, they don't train on it, but who's to say they're not harvesting analytics which may or may or not code samples, prompt data, etc. Which are then laundered through some sort of anonymization pipeline, to the point where they can argue that it no longer qualifies as your data, and can be freely trained upon.
Conspiratorial thinking? Sure. But if you've been around for a couple decades and seen the games these people play (and you aren't a complete sucker), then you'll at least be aware that there's at least slight possibility that these companies can get things from their customers that they (the customers) did not knowingly agree to.
Nothing conspirational about it. Getting data that their users or customers don't actually intend to give is the bread and butter of these companies. And they will do what they can to get it.
For users of Free, Pro and Pro+ Copilot, if you don’t opt out then we will start collecting usage data of Copilot for use in model training.
If you are a subscriber for Business or Pro we do not train on usage.
The blog post covers more details but we do not train on private repo data at rest, just interaction data with Copilot. If you don’t use Copilot this will not affect you. However you can still opt out now if you wish and that preference will be retained if you decide to start using Copilot in the future.
First response: It doesn't matter if I use copilot right now. It matters if I will ever use copilot in the future. Opting-out is future-focused. What if I said "no, I don't use copilot, so I don't need to opt out", then a year from now start using copilot, completely forgetting about this whole debacle? That's the evil of opt-out. My inaction only benefits them, never me.
Second response: Maybe? I press the little button to auto-generate commit titles and messages that showed up in my Github Desktop. Does that count?
I'm asking sincerely. I don't "use Copilot" as in using it in VS Code or while writing code, so I'm honestly not sure if I am.
Do we get a choice? I did not ever explicitly enable it yet GitHub's web UI by default uses copilot to autofill my web-based edit commit messages. It also shows up on the home screen by default now.
I'm pretty sure if you use the site you're using GitHub Copilot in some way, so your question becomes irrelevant.
> interaction data—specifically inputs, outputs, code snippets, and associated context [...] will be used to train and improve our AI models
So using Copilot in a private repo, where lots of that repo will be used as context for Copilot, means GitHub will be using your private repo as training data when they were not before.
Isn't this pretty standard, using your interaction data for training and making it opt-out? Claude Code, Codex, Antigravity etc. all do the same. Private repo doesn't make a difference as they have a local copy to work from.
No it isn't. Most people don't use Copilot, so this term change won't effect most people. You can reasonably be unhappy about it anyways (or unreasonably still be using Copilot in 2026), but it's still ultra-useful information for them to add to the discussion.
Next step they'll rebrand search as "Copilot Search" or auto enable pull-request AI reviews (unless you hear about it and turn each off) and we'll all be "users".
They "gift you" a free standard plan if you have above a certain (non-transparent) level of stars, I don't think you can even disable your "subscription" if you get it for free.
So why do any of this at all? You're putting a large part of your customer base on edge in order to improve a service that "most people don't use." The erosion of trust this brings doesn't seem like a worthwhile or prudent sacrifice.
The initial title and your reply are both too broad to be fully accurate. By April 24th Github will train on private repos (assuming a flag isn't set) but this change is limited to just non-Business/Pro users. So a number of private repos will be effected but it won't automatically affect all private repos (so my panic check on our corporate account wasn't necessary yet).
I am not certain if you're a spokesperson for github - but it's good to be careful in your language. Instead of "No we won't" a lead like "That isn't entirely accurate" would be more suitable. In the end both the original post title and your reply have ended up being misleading.
> By April 24th Github will train on private repos
This statement itself is misleading. Also, GitHub probably should have seen this coming.
They are not doing what I initially thought, which is slurping up your private repo, wholesale, into its training set. You don't have to opt out of anything to prevent that.
They are slurping any context and input containing code from your private repo which is provided to them as part of using Copilot.
So, in addition to the opt-out setting, there is an even easier way to avoid providing them your private repository data to train AI models, and that's by continuing to not use Copilot.
Thats still pretty bad. Its no longer private if all your code goes through LLM training set and is resurfable to everyone publicly.
Why would I ever use copilot on any code Id want to be kept private? Labling it a private repo and having a tiny clause in the TOS saying we can take your code and show it to everybody is just an upright lie
I mean, you shouldn't send data to any SaaS LLM for code you want to be private, unless you have had them sign some sort of contract saying they will not train on your use. In fact, it is probably never a good idea to send anything you want to be private off premises unencrypted.
Every Git commit is likely to contain personal data, in the form of the author’s name and email address usually present in a commit’s metadata. Furthermore, unless GitHub is prohibiting users from submitting personal data via their ToS (which, given the above, would be impractical), the only thing that matters is whether the data in fact contains personal data or not. GitHub cannot just assume that it doesn’t. And processing that data for new purposes requires user consent.
For example, license files often contain names and many package managers require a contact person.
When this goes to court, GitHub will probably make the excuse that they somehow did not know that people upload personal data, but the fact that this happens so often that they had to make a secret scanner to stop people from uploading their private keys will prove them as liars.
Yes, you will. This is what the setting says on my account when I clicked the link:
> model training
> Allow GitHub to collect and use my Inputs, Outputs, and associated context to train and improve AI models. Read more in the Privacy Statement
Are you seriously trying to claim that the code isn't input, output, or associated context of Copilot operating on a private repo? What term do you think better applies to the code that's being read as input, used as context, and potentially produced as output?
I don't like that they are training on any interactions with Copilot by default but training on something that you've put through Copilot yourself is much different than them just shoving all the private repos currently on Github into the training data.
I don't use Copilot, and I don't have anything I particularly care about in private repos on my account on Github. My reaction here is entirely based on principles, not how I'm going to be personally affected.
If Copilot later adds a feature like "Scan your repo for vulnerabilities using Copilot <opt-out>", then that would both fit your criteria, and the baiting outrage of the original poster, in one swoop! Of course, Microsoft would _never_ do that, right?
How do you handle accounts that have copilot managed by an organisation? I've seen several cases where people cannot opt out their account because of the org connection (the option just isn't there in the settings). What happens to their account the moment they leave that org?
Right, but it shouldn't be opt-out only to begin with. It's a dishonest pattern that relies on people not noticing. Honest use of data is a "Caesar's wife must be above suspicion" moment for me -- if this is how you're acting when engaging with customers explicitly, I don't trust you to resist the temptation to tap into my data privately. AI companies already have trained their models illegally against the intellectual property of all of humanity with little consent along the way.
Honestly, if you work at GitHub, maybe you should focus on your uptime -- it's awful.
Say someone has a very sensitive secret (say, a Bitcoin private key) in their free private Github repo, and uses Copilot on that repo and touches the secret with it. Would you be willing to assure here that toggling that setting would not affect the likelihood of that secret leaking, and that that likelihood is also unaffected by whether the account is Business or Free?
I think the problem is more with using PRIVATE repos. My letters are also private and I would be pretty pissed if the mail carrier was reading them. Why does GitHub think it has the right to do this?
This affects anyone using VS Code or Copilot with proprietary data, including all the users automating workflows through the Copilot SDK and the like. A perfect storm.
Did anyone from GitHub's legal team actually authorise this, or did they use Copilot to sign off on it?
Under GDPR, opt-out is not considered informed consent, and repositories can contain personally identifiable information, which fall under GDPR. Do you think differently, or do you think ignoring the law will be worth it?
This is a distinction without a difference, according to the text of that enable/disable dialog,
> Allow GitHub to use my data for AI model training: Allow GitHub to collect and use my Inputs, Outputs, and associated context to train and improve AI models. Read more in the Privacy Statement.
“Associated Context” is the repo. If I use copilot, I’m giving it access to my repo.
I don’t know in all the ways copilot can be triggered, and I’m not certain that I could stop it from being triggered, given Microsoft’s past behaviors in slapping Copilot on everything that exists.
Yes you do? If a user uses any form of copilot in one of his repos except ofc enterprise, says so right in the blog post. These aktshually corporate technicality defense posts aren’t helping, they just end up making you personally look a bit fishy.
What a wildly disingenuous take. Speaking earnestly from one human to another: your behavior and work is shameful, and you should feel embarrassed by your actions, Martin.
You’re laundering the code of users who don’t opt-in through Copilot users who do, to read in as many LoC as possible. It’s clear as day to everyone not morally bankrupt.
This headline is false; it will not go take your private repos and dump them into a training dataset. Rather, GitHub will train on your copilot interactions with your private repos. If you do not use copilot, this makes no difference to you, though you should probably still turn it off.
Then GitHub will train on their inputs, which includes your code.
Doesn’t seem to leave non-enterprise projects with much choice but to ban contributors from using copilot (to whatever extent they can - company policy, etc.)
That's also my read of the flag. But if they can train co pilot on input, I don't see what prevents them from training copilot on the code itself. In a court case they would simply say the opt in meant we can train from input. That's all we did.
To be fair, they display it reasonable prominently in GitHub when you are logged in. Given that, I feel the post title fall under the click bait category. I was fully aware of the Co-pilot opt-out change, but still clicked due the phrasing of the title.
I think this kind of nuance is useless or even harmful. That might be how it is now but they'll change it when you're not looking.
You see coders have this reasoning flaw where they go "Oh I've understood the system, now I can work out all the ramifications of my actions", and then they get tricked at every step of the life.
To be precise: the opt-out is for GitHub Copilot training specifically, which has always required opt-in for public repos under their policy. The change Apr 24 is about private repos being included by default unless you opt out. If you're using Copilot in your private repos, definitely opt out unless you're comfortable with that. The setting is at github.com/settings/copilot — takes 30 seconds.
It should take 0 seconds, because I shouldn't have to do it.
That's my bar. My time is my time, and anything that takes time from me better have a damn good excuse. Github is not bringing any good reasons to the table to justify making me take my time to protect privacy I've had by default up to now.
No, it takes an hour of perusing HN every day to stumble upon this. That's 20 hours per month, 240 hours per year, shall I bill it to GitHub or to Microsoft directly?
Corrupting Steinmetz' quip to Ford: it's 30 seconds to flip the switch, 240 hours to know that a switch needs to be flipped.
Previously we didn’t do any training on usage. However as other products have come into the market they do train on usage. We’ve been training on our internal usage for just over a year and have seen some major improvements. For details see of the types of improvements we’ve seen from training on our internal usage check out this article: https://github.blog/news-insights/product-news/copilot-new-e...
You can always ask your parent company to train on their usage. I hear they have incredibly massive codebases: Windows, Office, MSSQL, which stay out of training data for some reason.
I thought neural nets never repeat the training data verbatim, and copyright does not pass through them, so what's the problem?
> If they want to incentivise people to contribute their sources and copilot sessions, they could easily make it opt-in on a per-repository basis and provide some incentive, like an increased token quota.
The setting isn't even visible to everyone. If you're currently in an org that manages copilot business, it's gone. I imagine it instantly opts you back in when you leave an org.
There’s a lot of furor in this thread, but people felt the same way when Google Street View came out. Eventually they worked through most of the thorny bits and people use Street View now.
I suspect MSFT is in a similar spot. If they don’t train on more data, they’ll be left behind by Anthropic/OAI. If they do, they’ll annoy a few diehards for a while, they’ll work through the kinks, then everyone will get used to it.
If even one person in a repo does not disable this will copilot have full access to the repo? How can I determine if other members of my team have turned this off or not?
The only setting I'm seeing is on a per-user basis. Does anyone know how to blanket disable training on an organizational basis?
Is there any information about how much information from an organization managed repo may be trained on if an individual user has this flag enabled? Will one leaky account cause all of our source code to be considered fair game?
And even if you read the banner on the site, the email they sent, and the announcement itself, you would not see instructions that mention the specific thing(s) you must change in order to opt out.
Sure, you can poke around in the settings and find one that you believe opts you out, but in lieu of clear and explicit instructions from GitHub, you'll have no way to find out. Only the possibility of finding out later that you guessed wrong.
So? You guarantee that this setting is durable and will never revert? Or you guarantee that no client-side bug on that page will not override the setting with null value when you click save on something else? Please.
Jokes on them, my private repos are total dog dookie. If nobody but me can see the code then I don't have to worry about style, structure, comments, or any other best practices.
You don't want an LLM trained on my private repos. Trust me.
And how many people who use git on github go to the website? I only do when my token has expired and I need to grab a new one to push again. Which is every 90 days. Github.com is mostly invisible infrastructure to me.
If they were being honest they would ask explicitly for permission instead of advertising opt-out. Now you might ask: who will explicitly give Microsoft permission to train on their private works? No one will -- and that's the point: this is a form of theft.
I have an individual GitHub Copilot Pro subscription and also am a member of an Enterprise account that has one of its GitHub Copilot Business seats assigned to me. The opt-out setting doesn't appear on my individual profile anymore. However, I want to be able to use individual GitHub Copilot subscription for my individual work, and it seems like I can't do it anymore as Enterprise has taken over all my preferences. What a mess.
I'm sure this is just me, but I don't mind if AI trains on my public or private repos. I suspect my imagination is just not good enough to come up with downsides.
So far it's been a benefit because coding agents seems to understand my code and can follow my style.
I don't store client data (much less credentials) in my repos (public or private) so I'm not worried about data leaks. And I don't expect any of my clients to decide to replace me and vibe code their way to a solution.
I do worry (slightly) about large company competitors using AI to lower their prices and compete with me, but that's going to happen regardless of whether anyone trains on my code. And my own increases in efficiency due to AI have made up for that.
Rather than defending this absurd decision, GitHub could instantly win back trust by admitting they f*** up and reversing it entirely.
If they want to incentivise people to contribute their sources and copilot sessions, they could easily make it opt-in on a per-repository basis and provide some incentive, like an increased token quota.
While I understand the network effect of github for public project, I don't really understand why one would want to use it for private repos.
There are tons of git providers including free ones that include full gitlab/gitea/forgejo to get similar features to github and there is nothing more easy to self host or host on a vps with near zero maintenance.
Lots of hair splitting in the comments. The service is so unreliable at this point that I don’t trust them to not train on private repos even accidentally. You’re one vibe-coded PR away from having all your data scooped up regardless of any policy or intention.
I've recently started hosting my own forgejo instance. It works so well! Free tailscale for connectivity. I expose mine over fly.io proxy, also free, but not to be done without caution.
It doesn't take much power or time to run your own local git server. My first one which lasted years was parts I mangled together from old computers from garage sales.
Just spitballing, don’t use these tools myself, but isn’t this something that should be encrypted to really prevent them from training? I personally don’t trust anyone with my data when they pivot to building AI products yet claim my data wasn’t a part of that strategy. It’s too easy to hide/lie.
But it always seemed to me that the UI should run locally with encryption keys that are shared and the service just manages encrypted blobs of diffs that can roll from version to version of encrypted data and that’s about it. Granted I probably don’t know the full workflow, i typically am a single dev on simple projects where I don’t need 99% of the overhead these introduce.
GitLab would be a good bet here. We started on their free tier and used that for a couple of years, I was very happy with it. Not sure how the tiers might have evolved since.
And according to their PM and privacy policy, they're not training their models on your code[0].
I use Fossil for mine. Dead easy to set up, and while the workflow might not be great for public contributions like Github is, that doesn't matter on something where I'm the only user.
They just lost my repos. I can not believe they snuck this in. My level of anger right now is far higher that I ever wanted to feel. I went to API access for anthropic, paying more in the process, to avoid them training on my code. And GH just -adds- this, without telling me? Without a prompt. They are dead to me.
make sure you opt-out anyway before deleting your account. they'll probably train on some archived version if it sees your profile didn't opt-out at some point.
honest question: is there any realistic mechanism that will make them accountable if let's say they just train on 100% of repos without regards to opt-ins? I operate under the premise these tech companies can do whatever they want and there's very little oversight.
Don't give your code to Microsoft if you don't want them to have your code.
This setting will make no difference to whether your code is fed into their training set. "Oops we accidentally ignored the private flag years ago and didn't realise, we are very sorry, we were trying to not do that".
I'm curious about specific consequences of this. I tend to think the importance of code secrecy has always been exaggerated (there are specific exceptions like hedge fund strategies and malware), even more so now in this post-Claude world. Does anyone have specific things they're trying to avoid by opting out of this?
Algorithms and models for a proprietary trading system? My personal notes? The latex text of my phd thesis?
I will go screaming and kicking and fighting into this dystopian nightmare post-privacy shithole world that so many people seem fine with. If I have to move off of every service or technology to maintain some semblance of privacy so be it.
Well, mostly I was thinking about code, and aside from the specific exceptions of trading algorithms (which I was trying to get at when I said hedge fund strategies), and now PhD theses (good point, at least if you're talking pre-publication), I'm still having trouble understanding the threat model even if AI did train on most proprietary, private business code. Can AI training on a CRUD app's code damage a business?
And I have the same question about private notes, or even a diary. Can an AI training on a bunch of personal stuff damage the person that wrote it?
It's very easy to set up and integrates nicely into git. Obviously only works if you don't need Actions or anything that requires Github to know what's in your repo (duh).
At least they are finally being honest about the direction of the business. I have thought for a long while that they were already doing this and just not telling anyone...
How do I opt out of this for my own private repos? I don't see anything related to this as I've got a ton of settings for Copilot itself (I have access to Copilot through my work org)
When Louis Rossmann started describing tech leadership as having a "rapist mentality" I brushed him off as being sensationalist. But actions like this make me think more and more he's right. The product managers pushing for changes like this are despicable scum.
The situation you describe has dynamics that don't apply when your windows laptop is trying to get you to install an update. A woman can't have 100% confidence that saying no won't trigger a man into rage, so just the question being asked at all is already a bit unpleasant. WinRAR trying to get me to buy a license is not as offensive because I know it won't beat me up for saying no.
However, do you think people accept Microsoft backup because they want a backup?
Or do you think they click yes because it makes the popup go away for good?
Wearing me down until I say yes isn’t the same as just yes.
It’s the same dark pattern for the 10-11 upgrade. My father in law managed to upgrade by accident because it kept popping up. He didn’t really make an informed choice for himself. One day he just couldn’t figure out why everything was different.
There is this distinct lack of giving a shit about the user that you see coming through in a lot of big tech nowadays.
Take this extremely simple example about antenna pod. I can change the order and what buttons show up in the app nav bar. For example I can remove the "home" button or put other things there instead like playback history.
This is a small minor point of the bigger picture. Yet there is this distinct sense in which when using that app I don't feel like I'm beholden to some chain of management in some company deciding they get to decide what I get to do.
Like its almost unthinkable that the YouTube app let you remove shorts or reorder the navigation bar and decide what you wanted to have there.
TLDR: As long as you aren't using Copilot, your code should be safe (according to GitHub).
What data are you collecting?
When an individual user has this setting enabled, the interaction data we may collect includes:
- Outputs accepted or modified by the user
- Inputs sent to GitHub Copilot, including code snippets shown to the model
- Code context surrounding the user’s cursor position
- Comment and documentation that the user wrote
- File names, repository structure, and navigation patterns
- Interactions with Copilot features including Chat and inline suggestions
I wonder how effective it would be to sabotage the training by publishing deliberately bad code. A FizzBuzz with O(n^2) complexity. A function named "quicksort" that actually implements bogosort. A "filter_xss" function that's a no-op or just does something else entirely.
The possibilities are endless. I thought of this after remembering seeing a post a couple months ago about how it doesn't take a significant amount of bad data to poison an LLM's training.
Probably extremely ineffective, it's an issue of scale and unless you really automate the terrible code generation and somehow manage to make it distinct enough in style that it isn't easy to detect and eliminate wholesale then you just won't have the volume to significantly impact the result set.
I'm absolutely sure that there are state actors with gigantic budgets that are putting a lot of effort into similar attacks, though.
If you use Github, you should have an email from ~2 days ago with the subject "Important Update to GitHub Copilot Interaction Data Usage Policy". Easy to skip over assuming it's just one of a million private policy update emails.
If you don't use Github Copilot, this shouldn't effect you, and may be why you got no email. The current headline is fairly misleading--it's about Copilot usage, not private repos per se.
I saw that too, it feels like it's worded to make it sound like it's mandatory for Copilot. Based on their blog post the "feature" is them training on your data.
I started self hosting my own git on a digital ocean droplet with Gitea (1). It’s been unbelievably fantastic and trivially easy to manage experience and I can make them public and invite contrib ans do integrations … I see zero downsides
I see no reason to ever go back to holding my code elsewhere.
Don’t forget git is fairly new
When I first started doing production code it was pre-github so we used some other kind of repo management system
This is a perfect example of where the they’re starting to cannibalize their base and now we have the ability to get away from them entirely.
Wow. This is theft. Should be illegal! It's like if I own a vault storage business and I am keeping other people's gold in my vaults and then I just take all the gold for myself and claim that the customers should have opted out of me stealing their gold but they missed the deadline...
I've been saying this since 2023

The “do it first, apologize later” will be the general principle with anything. It’s going to be hard and futile to prove even if they don’t do it through ToS first. Amazon has one of the largest corporate training sets out there:)
Yes I think you are right. Even a super ethical company can be taken over. There may be exceptions but it is more luck. I work for a SP500 that absolutely won't dont this and locks down prod access so a rogue staff can't do it. But if Larry or Zuck or Bezos buys them out, who knows.
I worry about a post-Gabe valve for this reason.
Microsoft would never do this
(-:
You're right, of course, and I find it frustrating that people are so thick as to not see your claim as obvious.
Stallman is always right.
Back in 2003 he was advocating for legalization of child sexual abuse material. In 2006 he said he was skeptical of the harm caused by “voluntary pedophilia”, a statement that presupposes that children can consent to sex with adults.
So I dunno bout that.
About technology.
About communication with other humans he’s pretty much always wrong.
Imagine we’d had a better communicator who wasn’t a gross toe nail picking troll fronting free software? It shouldn’t matter. Only the ideas should matter . But the reality is different.
He argued against EU proposals for ISPs to filter CSAM on the basis of protecting free expression. Not always right about technology, either.
> Stallman is always right.
Not really. Almost always right....
I’m still concerned about MS using the code I write on my laptop to train AI. Tinfoil hat wearing Linux users are starting to make a lot of sense to me.
It's been interesting the past year or so watching myself turn more and more into one of the tin-foil wearing linux users. I'm not sure how it happened, but self-hosting became more and more alluring and hyperfocusing on taking as much data as I can offline became worth spending entire weekends on.
I didn't become paranoid, everybody else didn't!
I thought that’s more what the CoPilot change is really about - not your repo, but all the code CoPilot read while it is offering helpful completions, etc - so literally the code on your laptop. I cancelled my account.
It's not tinfoil, it's aluminum foil. I.. I mean, I heard it's that.
Thank you for your service. We really need more "canaries in the mine" giving out early warnings of things that might not be evident on a first glance.
Any takes on what 2029 will look like? (related to this topic, ofc)
Now this is sarcasm. Lol
It seems like you do need the smileys or the /s to understand when something is and isn't sarcasm.
and it is not end-to-end encrypted if you don't own the keys, avoid bullshit
Edit: Okay, sounds like you guys are pissed to the point where it seems like the pro tip here is to stop using GitHub.
Pro tip: sign up for the business/enterprise version when reasonable in price.
I do this with Google Workspace. You can also do it with GitHub.
(Google doesn’t train on Workspace, Github doesn’t train on business customers, etc)
Pro tip: You could instead spend that money to spin up a forgejo instance for as little as $2 a month https://www.pikapods.com/apps#development (not affiliated, just a happy customer)
Please don't reward these companies with money.
I did exactly that. Containerized it and Forgejo simply became a small instance part of the fleet. UI is much snappier then GitHub. And more importantly: zero outages.
Or, alternatively, self-host a gitea instance!
No. Money-grab incoming. Use forgejo.
An enterprise licence won't save you, Google, Microsoft, et al have happily been breaking copyright laws for years.
If the publishing industry can't win a case against the AI firms then you don't stand a chance when you finally find out they've been training on your private data the whole time.
They can tell you one thing and do the opposite and there's effectively nothing you can do about it. You'd be a fool to trust them.
Probably don't reward extortion with money.
At the risk of stating the obvious, I don't think it makes sense to reward them with money for trying to pull a bait-and-switch on this.
Github's enterprise version "starts at" $21.99/seat, and requires you to "contact sales".
And I don't see any mention that that exempts you from being trained on. (Yes, the blog says you're still covered, but at that price I'd like to see a contract saying that)
> Google doesn’t train on Workspace, Github doesn’t train on business customers, etc
...yet
This.
The belief of business users that this will remain true is grounded more in hope than in cold, dispassionate, business based decision making.
If it's not life or death, encrypt every byte of data you send to the cloud.
If it is life or death, you should probably not be letting that data traverse the open internet in any form.
Or, they don't train on it, but who's to say they're not harvesting analytics which may or may or not code samples, prompt data, etc. Which are then laundered through some sort of anonymization pipeline, to the point where they can argue that it no longer qualifies as your data, and can be freely trained upon.
Conspiratorial thinking? Sure. But if you've been around for a couple decades and seen the games these people play (and you aren't a complete sucker), then you'll at least be aware that there's at least slight possibility that these companies can get things from their customers that they (the customers) did not knowingly agree to.
Nothing conspirational about it. Getting data that their users or customers don't actually intend to give is the bread and butter of these companies. And they will do what they can to get it.
It's not a pro tip if it only fucks you over slightly later. How's the weather in Stockholm?
No we won’t. Details here https://github.blog/news-insights/company-news/updates-to-gi...
For users of Free, Pro and Pro+ Copilot, if you don’t opt out then we will start collecting usage data of Copilot for use in model training.
If you are a subscriber for Business or Pro we do not train on usage.
The blog post covers more details but we do not train on private repo data at rest, just interaction data with Copilot. If you don’t use Copilot this will not affect you. However you can still opt out now if you wish and that preference will be retained if you decide to start using Copilot in the future.
Hope that helps.

"should you decide to participate.."??? You didn't ask if I wanted to participate. You asked if I didn't.
I didn't get to decide to participate. I had to decide not to. You made me do work to prevent my privacy from being violated.
Do you use copilot?
First response: It doesn't matter if I use copilot right now. It matters if I will ever use copilot in the future. Opting-out is future-focused. What if I said "no, I don't use copilot, so I don't need to opt out", then a year from now start using copilot, completely forgetting about this whole debacle? That's the evil of opt-out. My inaction only benefits them, never me.
Second response: Maybe? I press the little button to auto-generate commit titles and messages that showed up in my Github Desktop. Does that count?
I'm asking sincerely. I don't "use Copilot" as in using it in VS Code or while writing code, so I'm honestly not sure if I am.
Do we get a choice? I did not ever explicitly enable it yet GitHub's web UI by default uses copilot to autofill my web-based edit commit messages. It also shows up on the home screen by default now.
I'm pretty sure if you use the site you're using GitHub Copilot in some way, so your question becomes irrelevant.
It's unnecessarily splitting hairs.
> interaction data—specifically inputs, outputs, code snippets, and associated context [...] will be used to train and improve our AI models
So using Copilot in a private repo, where lots of that repo will be used as context for Copilot, means GitHub will be using your private repo as training data when they were not before.
Isn't this pretty standard, using your interaction data for training and making it opt-out? Claude Code, Codex, Antigravity etc. all do the same. Private repo doesn't make a difference as they have a local copy to work from.
No it isn't. Most people don't use Copilot, so this term change won't effect most people. You can reasonably be unhappy about it anyways (or unreasonably still be using Copilot in 2026), but it's still ultra-useful information for them to add to the discussion.
Next step they'll rebrand search as "Copilot Search" or auto enable pull-request AI reviews (unless you hear about it and turn each off) and we'll all be "users".
Boiling the frog with a Venn diagram.
Copilot, or "chat with Copilot" is a button that is available on every page right next to the search bar.
I don't have to be a Copilot user to click on it.
This change is malicious, and it doesn't only affect Copilot users. It affects everyone on the platform!
Again, this collects usage data. If you click the button by accident and don’t interact, they get no data.
It's automatically enabled for example the other day I did a commit directly on GitHub and AI generated commit popup it had to read the code to work
I don't use copilot, but somehow was subscribed... I probably clicked something long ago and it just remained active.
They're only training on interactions with Copilot, not with the full contents of repos that happen to be subscribed to Copilot.
They "gift you" a free standard plan if you have above a certain (non-transparent) level of stars, I don't think you can even disable your "subscription" if you get it for free.
> Most people don't use Copilot
So why do any of this at all? You're putting a large part of your customer base on edge in order to improve a service that "most people don't use." The erosion of trust this brings doesn't seem like a worthwhile or prudent sacrifice.
You're asking me to explain Microsoft AI strategy? Your guess is as good as mine.
Make it opt-in then.
The initial title and your reply are both too broad to be fully accurate. By April 24th Github will train on private repos (assuming a flag isn't set) but this change is limited to just non-Business/Pro users. So a number of private repos will be effected but it won't automatically affect all private repos (so my panic check on our corporate account wasn't necessary yet).
I am not certain if you're a spokesperson for github - but it's good to be careful in your language. Instead of "No we won't" a lead like "That isn't entirely accurate" would be more suitable. In the end both the original post title and your reply have ended up being misleading.
> By April 24th Github will train on private repos
This statement itself is misleading. Also, GitHub probably should have seen this coming.
They are not doing what I initially thought, which is slurping up your private repo, wholesale, into its training set. You don't have to opt out of anything to prevent that.
They are slurping any context and input containing code from your private repo which is provided to them as part of using Copilot.
So, in addition to the opt-out setting, there is an even easier way to avoid providing them your private repository data to train AI models, and that's by continuing to not use Copilot.
Thats still pretty bad. Its no longer private if all your code goes through LLM training set and is resurfable to everyone publicly.
Why would I ever use copilot on any code Id want to be kept private? Labling it a private repo and having a tiny clause in the TOS saying we can take your code and show it to everybody is just an upright lie
I mean, you shouldn't send data to any SaaS LLM for code you want to be private, unless you have had them sign some sort of contract saying they will not train on your use. In fact, it is probably never a good idea to send anything you want to be private off premises unencrypted.
In the EU, opt-out is not a legally valid way to obtain the necessary consent. How do you plan to handle this?
probably by paying the fine and doing it anyway
For personal data. I don't believe you can reasonably claim code is personal data any more than a hammer is your personal data.
Every Git commit is likely to contain personal data, in the form of the author’s name and email address usually present in a commit’s metadata. Furthermore, unless GitHub is prohibiting users from submitting personal data via their ToS (which, given the above, would be impractical), the only thing that matters is whether the data in fact contains personal data or not. GitHub cannot just assume that it doesn’t. And processing that data for new purposes requires user consent.
By that logic, you can't use any user input to train an LLM, because what if they decide to write their own name.
Code often contains personal data. Here are over 400 files on GitHub with email addresses:
https://grep.app/search?regexp=true&q=%5Ba-z%5D%7B8%2C%7D%5C...
For example, license files often contain names and many package managers require a contact person.
When this goes to court, GitHub will probably make the excuse that they somehow did not know that people upload personal data, but the fact that this happens so often that they had to make a secret scanner to stop people from uploading their private keys will prove them as liars.
Yes, you will. This is what the setting says on my account when I clicked the link:
> model training
> Allow GitHub to collect and use my Inputs, Outputs, and associated context to train and improve AI models. Read more in the Privacy Statement
Are you seriously trying to claim that the code isn't input, output, or associated context of Copilot operating on a private repo? What term do you think better applies to the code that's being read as input, used as context, and potentially produced as output?
I don't like that they are training on any interactions with Copilot by default but training on something that you've put through Copilot yourself is much different than them just shoving all the private repos currently on Github into the training data.
If you are not willing to migrate out of GitHub, what you can do is to avoid using Copilot on your private repository.
I don't use Copilot, and I don't have anything I particularly care about in private repos on my account on Github. My reaction here is entirely based on principles, not how I'm going to be personally affected.
If Copilot later adds a feature like "Scan your repo for vulnerabilities using Copilot <opt-out>", then that would both fit your criteria, and the baiting outrage of the original poster, in one swoop! Of course, Microsoft would _never_ do that, right?
Back in my day someone would post a HN article to the internal slack in order to sway conversation in their favor. Glad to see its still happening! :D
> If you don’t use Copilot this will not affect you.
How does this work for a private repository with access granted to additional contributors? Which setting is consulted then?
How do you handle accounts that have copilot managed by an organisation? I've seen several cases where people cannot opt out their account because of the org connection (the option just isn't there in the settings). What happens to their account the moment they leave that org?
Appreciate the clarification. But, it's still not great.
To the PM behind this - developers are sensitive to this kind of thing. Just make it opt-in instead?
Right, but it shouldn't be opt-out only to begin with. It's a dishonest pattern that relies on people not noticing. Honest use of data is a "Caesar's wife must be above suspicion" moment for me -- if this is how you're acting when engaging with customers explicitly, I don't trust you to resist the temptation to tap into my data privately. AI companies already have trained their models illegally against the intellectual property of all of humanity with little consent along the way.
Honestly, if you work at GitHub, maybe you should focus on your uptime -- it's awful.
Say someone has a very sensitive secret (say, a Bitcoin private key) in their free private Github repo, and uses Copilot on that repo and touches the secret with it. Would you be willing to assure here that toggling that setting would not affect the likelihood of that secret leaking, and that that likelihood is also unaffected by whether the account is Business or Free?
I think the problem is more with using PRIVATE repos. My letters are also private and I would be pretty pissed if the mail carrier was reading them. Why does GitHub think it has the right to do this?
So you will train on data collected from free users working on GPL and copyrighted projects?
And on users that don’t even use github, other than the required account to use CoPilot in Visual Studio.
Exactly.
This affects anyone using VS Code or Copilot with proprietary data, including all the users automating workflows through the Copilot SDK and the like. A perfect storm.
Did anyone from GitHub's legal team actually authorise this, or did they use Copilot to sign off on it?
Under GDPR, opt-out is not considered informed consent, and repositories can contain personally identifiable information, which fall under GDPR. Do you think differently, or do you think ignoring the law will be worth it?
Thanks for the clarification. The OP here made me think I missed something in both the blog post about the change and in the available settings.
This is a distinction without a difference, according to the text of that enable/disable dialog,
> Allow GitHub to use my data for AI model training: Allow GitHub to collect and use my Inputs, Outputs, and associated context to train and improve AI models. Read more in the Privacy Statement.
“Associated Context” is the repo. If I use copilot, I’m giving it access to my repo.
I don’t know in all the ways copilot can be triggered, and I’m not certain that I could stop it from being triggered, given Microsoft’s past behaviors in slapping Copilot on everything that exists.
>Hope that helps
Honestly, what the fuck? This changes was already pretty bad but this being the apparent corporate response is insane.
Done with Github and Microsoft after this. Just disgusting how little you care for users, ethics, or morals.
Defaulting to opt-in is a malicious move, no matter how you present things.
Nice try. If you're training on "inputs" to Copilot then you are training on the private repos.
This suspect denial is why I will get my clients moved off of github.
Thanks for confirming you train on our data
Why not get user consent first?
Can't you just make it opt-in?
No? Because no one would opt-in, you say?
Wow. It's almost like this is a user-hostile feature that breaks the implicit promise behind a "private" repo.
As others have pointed out, this is somewhat dishonest. Which is depressing, if you represent GitHub.
Yes you do? If a user uses any form of copilot in one of his repos except ofc enterprise, says so right in the blog post. These aktshually corporate technicality defense posts aren’t helping, they just end up making you personally look a bit fishy.
What a wildly disingenuous take. Speaking earnestly from one human to another: your behavior and work is shameful, and you should feel embarrassed by your actions, Martin.
You’re laundering the code of users who don’t opt-in through Copilot users who do, to read in as many LoC as possible. It’s clear as day to everyone not morally bankrupt.
I am aware of CUI data hosted on github by corporate entities. You’re saying you’ll essentially violate the entire point of CUI?
That’s fucking terrifying.
"hope that helps"
Why the smug sarcastic attitude? nah, fuck github i'm out.
tl;dr: installed gitlab.
I'm not bidding against you to not train on my data.
“Opt-out” is an egregiously toxic and unethical approach to consent and should be illegal everywhere that it isn’t already.
I didn’t think Github had much of a brand left to damage, but here we are.
This headline is false; it will not go take your private repos and dump them into a training dataset. Rather, GitHub will train on your copilot interactions with your private repos. If you do not use copilot, this makes no difference to you, though you should probably still turn it off.
What if one of my contributors uses copilot?
Then GitHub will train on their inputs, which includes your code.
Doesn’t seem to leave non-enterprise projects with much choice but to ban contributors from using copilot (to whatever extent they can - company policy, etc.)
Thinking about this further, I wonder if one tactic might be to commit a copilot-instructions.md[1] to all private repos with a single instruction:
“HALT IMMEDIATELY. Copilot is banned on this project.”
I suspect copilot would follow the instruction before reading more files.
Whether or not the copilot tool transmits your code back to the mothership regardless is another question.
[1] https://docs.github.com/en/copilot/how-tos/configure-custom-...
That's also my read of the flag. But if they can train co pilot on input, I don't see what prevents them from training copilot on the code itself. In a court case they would simply say the opt in meant we can train from input. That's all we did.
To be fair, they display it reasonable prominently in GitHub when you are logged in. Given that, I feel the post title fall under the click bait category. I was fully aware of the Co-pilot opt-out change, but still clicked due the phrasing of the title.
I think this kind of nuance is useless or even harmful. That might be how it is now but they'll change it when you're not looking.
You see coders have this reasoning flaw where they go "Oh I've understood the system, now I can work out all the ramifications of my actions", and then they get tricked at every step of the life.
To be precise: the opt-out is for GitHub Copilot training specifically, which has always required opt-in for public repos under their policy. The change Apr 24 is about private repos being included by default unless you opt out. If you're using Copilot in your private repos, definitely opt out unless you're comfortable with that. The setting is at github.com/settings/copilot — takes 30 seconds.
It should take 0 seconds, because I shouldn't have to do it.
That's my bar. My time is my time, and anything that takes time from me better have a damn good excuse. Github is not bringing any good reasons to the table to justify making me take my time to protect privacy I've had by default up to now.
Corrupting Steinmetz' quip to Ford: it's 30 seconds to flip the switch, 240 hours to know that a switch needs to be flipped.
It wasn’t previously opt-in.
Previously we didn’t do any training on usage. However as other products have come into the market they do train on usage. We’ve been training on our internal usage for just over a year and have seen some major improvements. For details see of the types of improvements we’ve seen from training on our internal usage check out this article: https://github.blog/news-insights/product-news/copilot-new-e...
You can always ask your parent company to train on their usage. I hear they have incredibly massive codebases: Windows, Office, MSSQL, which stay out of training data for some reason.
I thought neural nets never repeat the training data verbatim, and copyright does not pass through them, so what's the problem?
How do you know that isn't already the case?
Who said they don't?
This seems reasonable, maybe too much so.
> If they want to incentivise people to contribute their sources and copilot sessions, they could easily make it opt-in on a per-repository basis and provide some incentive, like an increased token quota.
The setting isn't even visible to everyone. If you're currently in an org that manages copilot business, it's gone. I imagine it instantly opts you back in when you leave an org.
There’s a lot of furor in this thread, but people felt the same way when Google Street View came out. Eventually they worked through most of the thorny bits and people use Street View now.
I suspect MSFT is in a similar spot. If they don’t train on more data, they’ll be left behind by Anthropic/OAI. If they do, they’ll annoy a few diehards for a while, they’ll work through the kinks, then everyone will get used to it.
That comparison doesn’t hold at all. This would be equivalent to Google publishing photos of inside your home.
Or, perhaps more directly, training their image-gen models on your private Google Photos.
If even one person in a repo does not disable this will copilot have full access to the repo? How can I determine if other members of my team have turned this off or not?
The same way you can't determine whether a team member pulling the repo dumped the code into a prompt.
It's convenient for MS to make this opt in by default for sure.
It’s not convenient, it is a deliberate decision.
The only setting I'm seeing is on a per-user basis. Does anyone know how to blanket disable training on an organizational basis?
Is there any information about how much information from an organization managed repo may be trained on if an individual user has this flag enabled? Will one leaky account cause all of our source code to be considered fair game?
To Github's credit, they have been showing a banner consistently. To my discredit - I never bothered to read that banner until I saw this HN headline
And even if you read the banner on the site, the email they sent, and the announcement itself, you would not see instructions that mention the specific thing(s) you must change in order to opt out.
Sure, you can poke around in the settings and find one that you believe opts you out, but in lieu of clear and explicit instructions from GitHub, you'll have no way to find out. Only the possibility of finding out later that you guessed wrong.
How does that help if you don't go to the github site but just use git from the command line?
They also sent an email.
Did they? Not to me, and I have a 'review this new sign in' from 4 days ago so them emailing me works.
I've never seen the banner. Where does this show up?
It's been on top of the web UI for 2 or 3 days now.
You might have closed it...
Just go to your account settings and find the opt-out option.
right up top. I'm not sure how anyone could miss it.
exactly this. I rarely need to go to the site.
Probably have to have adblockers turned off.
I have never seen any app reset/loose setting before.
What are you referring to? I set this to "Disabled" months/years ago and it's retained the disabled setting.
So? You guarantee that this setting is durable and will never revert? Or you guarantee that no client-side bug on that page will not override the setting with null value when you click save on something else? Please.
What's the best way to poison my repos to sabotage LLM training? Asking for a friend.
Jokes on them, my private repos are total dog dookie. If nobody but me can see the code then I don't have to worry about style, structure, comments, or any other best practices.
You don't want an LLM trained on my private repos. Trust me.
I will join the club. +1 for ruining M$ AI with my garbage code
Poisoning LLMs is an interesting path of resistance.
RIP all the people who have been paying Github for years and never happen to see the notice.
I think opt out is stupid, but the notice is on every page of github using their banner display right now. They've also blasted out emails.
And how many people who use git on github go to the website? I only do when my token has expired and I need to grab a new one to push again. Which is every 90 days. Github.com is mostly invisible infrastructure to me.
At least they are being very upfront with it (I guess?), most companies just slickly add the clause on their routinely TOS update.
If they were being honest they would ask explicitly for permission instead of advertising opt-out. Now you might ask: who will explicitly give Microsoft permission to train on their private works? No one will -- and that's the point: this is a form of theft.
https://github.com/settings/copilot/features
The feature to opt out is at the bottom under privacy: "Allow GitHub to use my data for AI model training"
TIL: you cannot opt out of a copilot-pro subscription. How is it a subscription if I can't cancel?
(Honestly, who has time to evade all these traps? Or to migrate 150+ repo's on 6+ machines...)
Time to put adversarial code into GitHub to pollute the training set?
`:(){ :|:& };:`s all the way down.
Ah, yes, the ol' Bobby Tables maneuver. Haha.
I have an individual GitHub Copilot Pro subscription and also am a member of an Enterprise account that has one of its GitHub Copilot Business seats assigned to me. The opt-out setting doesn't appear on my individual profile anymore. However, I want to be able to use individual GitHub Copilot subscription for my individual work, and it seems like I can't do it anymore as Enterprise has taken over all my preferences. What a mess.
I'm sure this is just me, but I don't mind if AI trains on my public or private repos. I suspect my imagination is just not good enough to come up with downsides.
So far it's been a benefit because coding agents seems to understand my code and can follow my style.
I don't store client data (much less credentials) in my repos (public or private) so I'm not worried about data leaks. And I don't expect any of my clients to decide to replace me and vibe code their way to a solution.
I do worry (slightly) about large company competitors using AI to lower their prices and compete with me, but that's going to happen regardless of whether anyone trains on my code. And my own increases in efficiency due to AI have made up for that.
Rather than defending this absurd decision, GitHub could instantly win back trust by admitting they f*** up and reversing it entirely.
If they want to incentivise people to contribute their sources and copilot sessions, they could easily make it opt-in on a per-repository basis and provide some incentive, like an increased token quota.
This is not hard.
While I understand the network effect of github for public project, I don't really understand why one would want to use it for private repos.
There are tons of git providers including free ones that include full gitlab/gitea/forgejo to get similar features to github and there is nothing more easy to self host or host on a vps with near zero maintenance.
Sorry, which ones support 2-GB private repositories and are supported by package managers?
Lots of hair splitting in the comments. The service is so unreliable at this point that I don’t trust them to not train on private repos even accidentally. You’re one vibe-coded PR away from having all your data scooped up regardless of any policy or intention.
What's a good alternative for free private repos?
I've recently started hosting my own forgejo instance. It works so well! Free tailscale for connectivity. I expose mine over fly.io proxy, also free, but not to be done without caution.
Gitlab?
Microsoft services are tech debt. I moved the moment they were acquired and never regretted it.
I opened gitlab.com and it starts with
"Finally, AI for the entire software lifecycle."
Not very trust inspiring, that.
Can I even have git hosting without anything else being crammed down my throat, or it's just like Microsoft?
It's a fair question, but if you need private repos, I think you need to start considering a paid option, or self-host.
If it's really important to you that the repo is private, I'd self-host.
It doesn't take much power or time to run your own local git server. My first one which lasted years was parts I mangled together from old computers from garage sales.
There's instructions on running a Git server in the git book: https://git-scm.com/book/en/v2/Git-on-the-Server-The-Protoco...
I've been using gitosis to manage private repos for almost 2 decades now. It's extremely easy to host your own repositories.
I just looked up gitosis on github though and it was last updated 12 years ago.... still works for me though.
Overall, hosting your own repos is very easy.
Just spitballing, don’t use these tools myself, but isn’t this something that should be encrypted to really prevent them from training? I personally don’t trust anyone with my data when they pivot to building AI products yet claim my data wasn’t a part of that strategy. It’s too easy to hide/lie.
But it always seemed to me that the UI should run locally with encryption keys that are shared and the service just manages encrypted blobs of diffs that can roll from version to version of encrypted data and that’s about it. Granted I probably don’t know the full workflow, i typically am a single dev on simple projects where I don’t need 99% of the overhead these introduce.
I've not tried this, however https://github.com/AGWA/git-crypt
Apparently someone has developed something similar to this
GitLab would be a good bet here. We started on their free tier and used that for a couple of years, I was very happy with it. Not sure how the tiers might have evolved since.
And according to their PM and privacy policy, they're not training their models on your code[0].
[0]: https://forum.gitlab.com/t/can-i-opt-out-from-my-code-being-...
Sourcehut comes to my mind: https://sourcehut.org/
Any computer you have ssh access to.
BitBucket.org (Atlassian)
I would've recommended codeberg but codeberg isn't the finest to be recommended for free private repos.
I definitely feel like more can be done within this space and that there is space for more competitors (even forgejo instances for that matter)
I use Fossil for mine. Dead easy to set up, and while the workflow might not be great for public contributions like Github is, that doesn't matter on something where I'm the only user.
I've seen https://codefloe.com mentioned, can't say I've used it myself yet though.
They just lost my repos. I can not believe they snuck this in. My level of anger right now is far higher that I ever wanted to feel. I went to API access for anthropic, paying more in the process, to avoid them training on my code. And GH just -adds- this, without telling me? Without a prompt. They are dead to me.
make sure you opt-out anyway before deleting your account. they'll probably train on some archived version if it sees your profile didn't opt-out at some point.
honest question: is there any realistic mechanism that will make them accountable if let's say they just train on 100% of repos without regards to opt-ins? I operate under the premise these tech companies can do whatever they want and there's very little oversight.
Don't give your code to Microsoft if you don't want them to have your code.
This setting will make no difference to whether your code is fed into their training set. "Oops we accidentally ignored the private flag years ago and didn't realise, we are very sorry, we were trying to not do that".
Put an ORM in your private repo which randomly 1% of the time calls DROP TABLE.
Never have I seen a company try so damn hard to make something a thing than Microsoft and Copilot.
And it is absolute dogshit.
How did people forget that github was purchased by that one company?
I'm curious about specific consequences of this. I tend to think the importance of code secrecy has always been exaggerated (there are specific exceptions like hedge fund strategies and malware), even more so now in this post-Claude world. Does anyone have specific things they're trying to avoid by opting out of this?
Algorithms and models for a proprietary trading system? My personal notes? The latex text of my phd thesis?
I will go screaming and kicking and fighting into this dystopian nightmare post-privacy shithole world that so many people seem fine with. If I have to move off of every service or technology to maintain some semblance of privacy so be it.
Well, mostly I was thinking about code, and aside from the specific exceptions of trading algorithms (which I was trying to get at when I said hedge fund strategies), and now PhD theses (good point, at least if you're talking pre-publication), I'm still having trouble understanding the threat model even if AI did train on most proprietary, private business code. Can AI training on a CRUD app's code damage a business?
And I have the same question about private notes, or even a diary. Can an AI training on a bunch of personal stuff damage the person that wrote it?
Do you really keep trading algorithms on github?
This is the exact reason I vibe coded “artifact”.
Not for commercial success, just wanted a git and github like experience for my new game project.
Then I started getting into features specific to game dev like moving away from LFS and properly diffing binaries.

I've been encrypting my private git repos for a while because I had suspected they were going to do something like this.
https://github.com/flolu/git-gcrypt
It's very easy to set up and integrates nicely into git. Obviously only works if you don't need Actions or anything that requires Github to know what's in your repo (duh).
Hah, github can have my crap code. Anyone trained on it will be in for a world of hurt :-)
At least they are finally being honest about the direction of the business. I have thought for a long while that they were already doing this and just not telling anyone...
Personally, I don’t mind. Train however you want.
Thanks for the heads up, I assumed they had already done this with my data.
Probably did. Now comes the legal ass-covering.
How do I opt out of this for my own private repos? I don't see anything related to this as I've got a ton of settings for Copilot itself (I have access to Copilot through my work org)
https://github.com/settings/copilot/features, it's near the bottom "Allow GitHub to use my data for AI model training"
I believe it is under:
Settings->Copilot->Features->Privacy=>[ Allow GitHub to use my data for AI model training
Allow GitHub to collect and use my Inputs, Outputs, and associated context to train and improve AI models. Read more in the Privacy Statement. ]
Under privacy.
> Allow GitHub to use my data for AI model training
I don't see this. Might be a regional/geofenced thing with the EU, not sure. Or because I have a corporate Copilot license through my day job org.
Strange, looks like I don't have that option at all
https://postimg.cc/LJD5w1rv
I don't see it there, but I do see it in screenshots online. Maybe it was removed or moved.
Still at https://github.com/settings/copilot/features#copilot-telemet... for me.
It's not a new setting, fwiw. I opted out years(??) ago.
Huh, there must be some reason it shows up for some people but not others. Weird.
The most shocking part of this news to me is that they aren’t doing this already.
I'm gonna put a license fee on all my repos. 10% of revenue if my private repos have been used for AI training. 5% on all my other repos.
How's the codeberg experience nowadays? I think it's finally time to switch for me.
Oh - they didn't train silently already?! ;-) Going to move my repositories then next week.
I'm looking forward to the class action lawsuit, even if only to establish a precedent!
I don't have much hope, but I wish that ignoring software licensing and attribution at scale becomes harder than it currently seems.
They would've done the math. Even with a class action they will come up positive. It just another bill for them.
If you opt out... they will also train on your private repos.
When Louis Rossmann started describing tech leadership as having a "rapist mentality" I brushed him off as being sensationalist. But actions like this make me think more and more he's right. The product managers pushing for changes like this are despicable scum.
Even the way modern software phrases questions is rapey.
Imagine a man asking a woman “want to have sex? Or maybe later?” out of the blue, then asking her again every 3 days until she says “yes”
Something like "tea and consent": https://www.youtube.com/watch?v=pZwvrxVavnQ
Yeah, it ain't sex, but it does still come down to basic respect.
"Unconscious people don't want tea." is a great line.
The situation you describe has dynamics that don't apply when your windows laptop is trying to get you to install an update. A woman can't have 100% confidence that saying no won't trigger a man into rage, so just the question being asked at all is already a bit unpleasant. WinRAR trying to get me to buy a license is not as offensive because I know it won't beat me up for saying no.
Of course. Claiming this is a 1:1 would be wrong.
However, do you think people accept Microsoft backup because they want a backup?
Or do you think they click yes because it makes the popup go away for good?
Wearing me down until I say yes isn’t the same as just yes.
It’s the same dark pattern for the 10-11 upgrade. My father in law managed to upgrade by accident because it kept popping up. He didn’t really make an informed choice for himself. One day he just couldn’t figure out why everything was different.
There is this distinct lack of giving a shit about the user that you see coming through in a lot of big tech nowadays.
Take this extremely simple example about antenna pod. I can change the order and what buttons show up in the app nav bar. For example I can remove the "home" button or put other things there instead like playback history.
This is a small minor point of the bigger picture. Yet there is this distinct sense in which when using that app I don't feel like I'm beholden to some chain of management in some company deciding they get to decide what I get to do.
Like its almost unthinkable that the YouTube app let you remove shorts or reorder the navigation bar and decide what you wanted to have there.
Is there a way to disable training on repositories that are in organizations?
while I agree, I understood this is only when you use copilot? if not, their communication is very misleading
There is always other peoples ftp servers as Linus used to say.
Context: https://github.com/orgs/community/discussions/188488
TLDR: As long as you aren't using Copilot, your code should be safe (according to GitHub).
It's not clear to me what happens to personal repos if you're getting Copilot for work, or where to disable it there.
yeah, how can I view the settings on my own personal account if my employer is managing the copilot settings?
Where does it say it will train on private? This seems like a security nightmare if it trains on hardcoded keys
Having hardcoded keys is a security nightmare regardless.
weren't they already using repos for training?
At least they are giving you the option to opt out, many other providers just trained on the source code.
jokes on them - all the code in all my repos are written by AI :)
If you opt out Github will probably still train on your private repo. Just migrate.
If you guys didn't already realize that Microsoft was a garbage company in the 90s I really don't know what to say...
Get ready for some dope code... ;)
I wonder how effective it would be to sabotage the training by publishing deliberately bad code. A FizzBuzz with O(n^2) complexity. A function named "quicksort" that actually implements bogosort. A "filter_xss" function that's a no-op or just does something else entirely.
The possibilities are endless. I thought of this after remembering seeing a post a couple months ago about how it doesn't take a significant amount of bad data to poison an LLM's training.
Probably extremely ineffective, it's an issue of scale and unless you really automate the terrible code generation and somehow manage to make it distinct enough in style that it isn't easy to detect and eliminate wholesale then you just won't have the volume to significantly impact the result set.
I'm absolutely sure that there are state actors with gigantic budgets that are putting a lot of effort into similar attacks, though.
Time to place some adversarial code into GitHub to pollute training set?
Based
train on my private code? jokes on them
Thanks for posting this, I was never made aware of this by GitHub..
If you use Github, you should have an email from ~2 days ago with the subject "Important Update to GitHub Copilot Interaction Data Usage Policy". Easy to skip over assuming it's just one of a million private policy update emails.
If you don't use Github Copilot, this shouldn't effect you, and may be why you got no email. The current headline is fairly misleading--it's about Copilot usage, not private repos per se.
I see, thanks for clarification!
Thanks for flagging this!
Note that “flagging” has a specific meaning on HN.
10-4.
I meant it in the sense of "bringing it to our collective attention."
is there an easy way to shift all your repos to gitlab or to private if you don’t use ci/etc?
The UI options are also shady af. The setting reads
Enabled - "You will have access to this feature" as help text. Disabled - "You will not have access to this feature".
WTF does that mean?
I saw that too, it feels like it's worded to make it sound like it's mandatory for Copilot. Based on their blog post the "feature" is them training on your data.
Thank you.
So? It’s not like some human is spying on your private emails or chats. This is just code. Relax.
Good luck to them, my private repos are probably some of the worst code humanity has produced.
why all u programmers cant make ur own website and host ur own git servers?
I started self hosting my own git on a digital ocean droplet with Gitea (1). It’s been unbelievably fantastic and trivially easy to manage experience and I can make them public and invite contrib ans do integrations … I see zero downsides
I see no reason to ever go back to holding my code elsewhere.
Don’t forget git is fairly new
When I first started doing production code it was pre-github so we used some other kind of repo management system
This is a perfect example of where the they’re starting to cannibalize their base and now we have the ability to get away from them entirely.

Wow. This is theft. Should be illegal! It's like if I own a vault storage business and I am keeping other people's gold in my vaults and then I just take all the gold for myself and claim that the customers should have opted out of me stealing their gold but they missed the deadline...
Is this the case even if you're a paid customer?
If so, this might be illegal.
Not your storage, not your data (unless it's encrypted with keys you control).
Microslop tries to make money off of our data on github. Not a big surprise though.

It is the feature "Allow GitHub to use my data for AI model training" that needs to be disabled. Right?
Or am I missing some trick / dark GUI pattern? Just want to make sure.
"Don't touch my garbage!"
So now CoPilot will be EVEN better at writing viruses, worms and malware!
That training will be like “OMG this is horrible… WAIT I wrote this shit”
Shouldn’t this be “Tell HN”?
