Copilot won’t send your data down a path that incorporates it into training data. Not unless you do something like Bring Your Own Key and then point it at one of the “free” public APIs that are only free because they use your inputs as training data. (EDIT: Or if you explicitly opt-in to the option to include your data in their training set, as pointed out below, though this shouldn’t be surprising)
It’s somewhere between myth and conspiracy theory that using Copilot, Claude, ChatGPT, etc. subscriptions will take your data and put it into their training set.
Also, this conspiracy requires coordination across two separate companies (GitHub for the repos and the LLM providers requesting private repos to integrate into training data). It would involve thousands or tens of thousands of engineers to execute. All of them would have to keep the conspiracy quiet.
It would also permanently taint their frontier models, opening them up to millions of lawsuits (across all GitHub users) and making them untouchable in the future, guaranteeing their demise as soon a single person involved decided to leak the fact that it was happening.
I know some people will never trust any corporation for anything and assume the worst, but this is the type of conspiracy that requires a lot of people from multiple companies to implement and keep quiet. It also has very low payoff for company-destroying levels of risk.
So if you don’t trust any companies (or you make decisions based on vague HN anecdotes claiming conspiracy theories) then I guess the only acceptable provider is to self-host on your own hardware.
This is going to be the same disruption as Airbnb or Uber. Move fast and break things. Why would you expect otherwise?
The key question from the perspective of the company is not whether there will be lawsuits, but whether the company will get away with it. And so far, the answer seems to be: "yes".
The only exception that is likely is private repos owned by enterprise customer. It's unlikely that GitHub would train LLMs on that, as the customer might walk away if they found out. And Fortune 500 companies have way more legal resources to sue them than random internet activists. But if you are not a paying customer, well, the cliche is that you are the product.

And companies are conspirators by nature, plenty of large movie/game production companies manage to keep pretty quiet about game details and release-dates (and they often don't even pay well!).
I genuinely don't understand why you would legitimately "trust" a Corporation at all, actually, especially if it relates to them not generating revenue/marketshare where they otherwise could.

So it’s a “myth” that github explicitly says is true…
I guess if you count users explicitly opting in, then that part is true.
I also covered the case where someone opts-in to a “free” LLM provider that uses prompts as training data above.
There are definitely ways to get your private data into training sets if you opt-in to it, but that shouldn’t surprise anyone.
Or the more likely explanation: That this vague internet anecdote from an anonymous person is talking about some simple and obvious code snippets that anyone or any LLM would have generated in the same function?
I think people like arguing conspiracy theories because you can jump through enough hoops to claim that it might be possible if enough of the right people coordinated to pull something off and keep it secret from everyone else.
The existence of the ai generated studio ghibli meme proves ai models were trained on copyrighted data. Yet nobody’s been fired or sued. If nobody cares about that, why would anybody care about some random nobody’s code?
