On a different note... After reading the library of Congress response to the White House response here http://www.loc.gov/today/pr/2013/13-041.html I'm not sure what their actual response is.
I think they're saying something like this: "We did our job as prescribed by the law - we went through an extensive public comment and hearing process, and we produced an exemption that interpreted the available legal arguments as fairly as possible. Even if it would be nice to make unlocking legal, we only have the power to interpret existing laws; changing the laws is up to the rest of you."
