Look, I love the law as much as my fellow citizen but this is ridiculous. If you don't like the restrictions placed on you by Amazon,
don't obey them! Just break the DRM and give your books to whoever you please. Until Amazon actually manages to track and prosecute people who do this, which doesn't exactly seem likely, you haven't lost anything at all.
You are a human with free will. You can choose to do whatever you think is ethical and rational. If you think it's ethical to give books to other people, and you aren't going to suffer for it, then why aren't you doing it? I think it's really weird that we can sit here on Hacker News and talk about these arbitrary restrictions that Amazon has made as if they are actually restricting something. They are restrictions in name only.
