Great comment. Those who try to excuse book burning cannot be doing it in good faith, this is the acid test.

If AMZN, et al. were burning books in good faith, they would be open about it, point to the party responsible for it, and provide a list of the burned books to allow the community to organize, scavenge and scan the endangered publications. Keeping everything secret is a proof of maliciousness.

Preserving books and providing easy access to the information in them is of utmost importance, this is certainly understood by the public and private entities who could do something positive about it - their actions in the opposite direction should be a wake up call, they're on the wrong side of this issue.
