Anthropic was sued successfully for training on books, the law still applies to them

When I write fizzbuzz do I owe royalties to the inventor of fizzbuzz? Is my brain copyright thieving because I can write out the song lyrics from memory?

They got sued for downloading pirated books and not for using them for training. Huge difference.

Indeed, the court actually explicitly held that Anthropic had the right to train their AIs on books, so long as they paid for them.

I think if you write fizzbuzz and then sell it, without attribution, and it goes against the original fizzbuzz license, then you’re infringing.
