This is physically bought, scanned, books. Not covered by this case is what they’re allowed to do with that model, eg. charge people for access to it.
Maybe controversial, but compared to meta pirating books, claiming it makes no difference, and that each book is individually worthless to the model (but the model is of course worth billions), is it wrong that I’m like “hmm at they’re least buying books”?
As others say, there should be specific licensing, so they actually need to pay a cost per book, set by the publisher, specifically to legally include it in their model, not just shopping as humans but actually an llm skin suit slave.
