Given that, by the DMCA, it is illegal for you to transmit information that describes how to bypass copy protection, yes, the prohibition of circumvention is fucked beyond belief. You can't legally break it unless you learn how to do it for yourself (because teaching someone else how to do it is a criminal act), which puts even the most basic shit like "it's 100% legal for you to make a backup of your legally purchased media" (which it is, in the US, at least for now!) entirely outside the realm of possibility for most people. What good is my legal right to make backups if the backups stop working at exactly the same time the original stops working -- i.e., whenever the hell the rightsholder decides to turn off the authentication server?
