A Real Fair Use Paradox

I've been a fan of fair use since the days of Negativland; I had an original copy of the U2 single. These days I find some of the Creative Commons stuff very illuminating, and I find some of it moronically ideological. Cory Doctorow is usually way too ideological for my tastes, but this is a really great, succinct analysis of the pretzel of contradiction a Los Angeles museum recently twisted itself into with an exhibit on fair use.
