There is another insidious issue here - how do we know we're getting the real ebook when we first buy it? Maybe the copy of Animal Farm you just bought is the Black Socialist Dictator Born in Africa-Friendly version. Just like downloading code or programs from the Internet, maybe we need to start publishing MD5 checksums of e-books, on an independent site. Better yet, embedded digital signatures, signed using the private key of the publisher! Ain't capitalism great? I just invented a whole new industry!
