I support this in principle, but doesn't Amazon require that you not sell the book anywhere for less than the Amazon price? I'm pretty sure that means you can't give it away for free, either. I think that's why, although some books that are sold for money on Amazon are creative commons licensed, you won't generally find them on the authors' websites. It's legal, but I think it's a violation of the author or publisher's contract with Amazon to do that. 3rd parties can make such books available, though... legally, at least. In that situation, Amazon's TOS (assuming it has something like "thou shalt not redistribute any books purchased from Amazon without Amazon's permission") for ebook buyers would violate the clearly stated book license, so the TOS would become void, right?
