yes. in the sense that they probably wouldnt want to do this but the law forces them to do an extremely dumb thing.
they're paying for the books, no shady things going on there. whether the publishers should deserve more than a single copy's worth is a separate question.
having the law such that its illegal to scan a book and then keep it, but legal to scan it and destroy it - gg no re there, law people retardmaxxed themselves as they tend to do with anything related to digital data.
Law aside, destructive scanning is cheaper and easier. Cutting the book into individual pages would be happening regardless, because that is the easiest, fastest, cheapest way to scan it.
