99.99999% of the time libraries don't want donated books. Honestly don't know if they ever want them (outside of genuinely rare/interesting ones, and even then). Their collections are usually meticulously curated and are basically the children of whomever is currently responsible for them. Libraries throw away books at a prodigious rate as they wear, or their circulation numbers drop, or because they just run out of space.

Honestly I have no real issue with people destroying (most) books. It's 2026 we have access to printers and presses, we can literally make more books on demand, and again for the V A S T majority of books that's more than good enough (again, not counting anything rare/valuable/interesting but also at that point they kinda cease to become just "books" as the value is more tied than the object itself than the text within)

What I have a massive issue with is them hoarding this information, and/or very, VERY, likely breaking any licensing the book may be under. And on top of that seemingly doing a fucking horrible job at actually creating something worthwhile from this massive waste of man-hours and resources.
