Wonderful for spirited tales of rebellious creativity; infuriating for woolly logic and wild overclaims (who knew graffiti “inspired amazing new technologies”?). Arguing for an open-source world, Mason flits from a WWII jetty with its own stamps, to tagging Air Force 1, to the DJ nun who inspired Mancuso. Colourful, intriguing, but needs a remix before it's a solid argument about copyright.
