I agree that it should be illegal to block legal rights, but it happens all the time. Companies often expect you to sign contracts that eliminate rights. I'll bet Iphone users have already clicked on a EULA that prevents them exercising any of these new fair use rights.

Also, it is nice to have some additional clarification on what the DCMA actually means, but I'd prefer it if laws were clear enough that we knew what was illegal when the law is first passed.

Did I just hear Jobs sobbing in the corner?

This ruling should simultaneously focus on making the producers of "DRM damaged" files provide unencrypted versions of the same for free, or provide the tools to do so freely to all purchasers without further "EULA" restrictions.
