> Meta clearly enganged in copyright enfringement when they torrented books that they hadn't purchased. That is enfringement already before they started training on the data. That doesn't make the training itself enfringement though.

What kind of bullshit argument is this? Really? Works created using illegally obtained copyrighted material are themselves considered to be infringing as well. It's called derivative infringment. This is both common sense and law. Even if not, you agree that they infringed on copyright of something close to all copyrighted works on the internet and this sounds fine to you? The consequences and fines from that would kill any company if they actually had to face them.
