Creators are free to choose to spend their time doing creative work, or not, as we please. I'm going to keep writing for the public, and so are lots of other people, and we don't care if you do or not. Amazon or anyone else can redistribute our work; that way it reaches more people. They won't have much luck selling it when you can just download it for free.

If you think the world owes you something in return for spending your time writing, you should take your ball and go home. We have a civilization to preserve here that copyright is threatening — children to educate, medical treatments to deliver, historical films to copy onto non-rotting stock, private communications it's intolerable to scan for forbidden information on which the government has granted you a monopoly — and any one of these is more important than what you think you deserve.

Our intellect is not your property.
