they really should not be allowed to get away with this.
Im happy I only buy books where I get a DRM free copy
Who's going to "enforce" this? The UN? (HAH)
The only way to force this issue is to "pirate before you buy-it" and save your money. Hard to get screwed by fake purchase buttons if you dont buy, and hit libgen, torrents, and usenet.
Libgen works instantly, every time.
