Why? Couldn't they resell or give away the books after scanning them?

It's less work if you use a destructive method. They rip the spine off to get individual flatter sheets instead of scanning a bound book.

Per the courts, it actually helps their "fair use" case if they destroy the book instead of re-selling it.

chop off the spine and you can use an automated scanner. to keep the book intact you'll need a flatbed scanner and an operator.
