It's important to note that you don't actually buy e-books from Amazon, you license the right to read, and when that license is revoked/cancelled, those books are no longer available to you.
I wonder if some large organisation (EU?) could force a change in this idea? It does seem like an end-run around so much in the way of consumer rights.
Makes me wonder. What happens if you just don't connect your kindle to the net? I have a wifi only kindle which I never connect to the internet because I don't have a wifi connection anymore so I usually keep a local repository of my ebooks which I just drop on my kindle when I want to read them. Is the DRM contained in the azw and mobi files eventually going to stop me from opening them unless I connect to a wireless network?
I guess I never really considered that. Under what terms might that license be revoked/cancelled? It appears Amazon also lets you "rent" e-books for a certain amount of time. I suspect most people would assume that the high cost alternative to "renting" would be "buy to own". Especially considering the fact that the Kindle books typically cost the same (occasionally even a little bit more) than the physical books.
