Rare or not, destroying books is in itself a morally repugnant act. I don't know man, it's not so long ago we used to view nazi book burnings as an archetype of evil. Today companies are offering book-burning-as-a-service and it hardly causes a stir.
Bearded German man was right.
Is it destruction or format shift? Technically the books still exist; just that they're now digital. There's no content loss (what I imagine comprises a "book") unless any digitization is then deleted.
Well, there's a difference between destroying books to erase knowledge and control people, and destroying books because it's cheaper.
Easy claim to make when you’re not responsible for storing those books.

It's a routine act in any publisher stock management.
