If they're training LLMs on books found on park benches, we don't have a problem. That's obviously not what we're talking about though.

My point is "the legal owner of the book has to allow you to read it" is not true

I will accept the argument they got the source material in a way where someone broke American law. I really do not think they've broken any laws whatsoever in terms of using it for LLM training

> they got the source material in a way where someone broke American law

Isn't inducing or offering someone incentives to break laws illegal by itself? I'll admit that isn't specifically an IP law violation, but it can't possibly be kosher.

For example if a buyer of goods can reasonably be expected to know the goods were stolen, they can also be charged. Isn't this the same thing?
