I believe they all trained on pirated work, because there's no other way to get enough material (other than obeying the law and paying for it), but I can't say I'm absolutely certain about that. It's hard to be sure of your sources these days.
I do know there are other lawsuits, but they seem to turn on different fine points of copyright law, so winning the Anthropic one doesn't mean that they will all go the same way. There was a big news story a few months ago saying that Meta didn't just train on pirated databases, but it was revealed in discovery that they had discussed it by email (or text, but anyway, it was in writing), and went so far as to talk about destroying the databases, thus confirming that they did it and knew it was illegal. But then the news cycle moved on and I've heard nothing else. And, of course, I have to trust the reporting that this was true, which is a problem these days.
We've been told that the Anthropic payout is coming in installments and the first checks will go out in November. I don't even know yet how much mine is supposed to be, but I guess I'll know a little more then.
