Quote by Eben Moglen, wikipedia:
On the subject of Digital Rights Management, Moglen once said, "We also live in a world in which the right to tinker is under some very substantial threat. This is said to be because movie and record companies must eat. I will concede that they must eat. Though, like me, they should eat less."
So, will we have to be reduced to changing the titles and metadata of our de-drmed books so that they won't be detected? Or stop buying drm at all? (good option) Because I sure as hell am not going to buy anything twice just because it's 'illegal' to move it to another device.
