Re: DRM
The customer has the right to pay for the license. If you want to own a book and not care about DRM then buy it in paper form. Or print it.
Before the downvote brigade comes, I hate DRM as much as any Reg reader, but there's a clear distinction between licensing and owning something. With digital media (software, music, movies, books and such) you just buy a license, you don't own said media.
