Ai companies don't use ebooks, because they are more expensive than second hand books

They absolutely do. Meta torrented 81 terabytes of ebooks. They just have no incentive to pay when the law looks the other way.

The entire ironic thing here is that a huge part of those 81 terabytes of ebooks that Meta torrented were directly pirated books from Anna's Archive.

I meant paid ebooks. That's probably what the commenter refers to, because that's what publishers want. Obviously ai companies don't want to pay so they try to use pirated ebooks

On Amazon right now, retail prices for e-book copies are higher than for the corresponding paperbacks.

This is exactly why Amazon has also been doing this acquisition and destructive scanning of millions of books for some time now.

i imagine its because the doctrine of first sale does not apply to ebooks.
