> In practice, you usually need to demonstrate that you were harmed by an action to bring it to court.

I think this is true for copyright infringement damages. But is a GPL violation a copyright or a contract issue? And unlike copyright, the fix isn't damages to compensate the rightsholder, but to uphold the license.

> So we would need the author of a GPL'd repository to sue, with proof that copilot copied and pasted their code.

What happens if multiple authors wait and see, and then jointly sue? At that point, removing a single repo isn't enough.

That's not true. Courts won't consistently mandate that people relicense their code that includes GPLed stuff. They'll make you pay a fine and remove the code.
