The problem is that Kindle users probably did give explicit permission (for some definition of explicit permission). I'm sure there's a clause in the ToS that allows Amazon to delete content that you've purchased. This is why there has to be clear law that says that one owns the digital content on ones ebook reader. Courts might interpret that you already do, but clear statue law would be very clarifiying. Remember if the law says one thing, and you agree (via a T&C or contract) to another, then the law wins. You cannot sign something away if the law says you cannot sign the thing away. No country is a pure libertarian utopia.
