Street Art and critical statements

I've just found (via the friends at The Influencers) an extremely interesting article on the censoring of a Blu's wall at the Museum of Contemporary Art in Los Angeles.
It underlines many crucial points about the commercial/critical dichotomy of contemporary street art: censorship; curatorship; engagement; radical critic; to be in the streets or in museums.
Enjoy!
