Imagine if they broke it down to each distinct source, that'd be several billion cases of copyright infringement (though it's going to be determined by what courts think and that often comes down to "who can afford the best lawyers" in practice if not intent).

Apparently if I use lib-gen, that's copyright infringement and I'm exposed to legal risk but it seems fine to download all of it if your intent is "train an AI" so far.
