Copyright and Fair Use LR

16. At a local electronics show, a teacher buys a machine that defeats the copy protection on DVDs, CD-ROMs, and just about everything else. She lets her students use it so they can incorporate clips from rented DVDs into their film genre projects. This is fair use.

This is the one that really surprised me.  Not only was the author really flippant about the answer (that you can rip content for educational purposes), but the answer itself surprised me.  Digital protection is supposed to be like a safe - either you can't get in at all, or you can only get in under the owner's circumstances.  Cracking the digital protection, even for educational purposes, would be like breaking the padlock on somebody's door. It seems to me that the excuse that technological blocking and legal blocking are different things is a bit off.  The content is blocked for a reason - you wouldn't tell somebody they couldn't put a password on their own content.
