anti-DRM movement
Defective by Design is an anti-DRM campaign by the Free Software Foundation. The “About” page explains the problems with DRM software quite succinctly, and it’s important enough for everyone to spend a few moments reading it.
This t-shirt design from GoodStorm is a delightful parody of Apple’s iPod ads, and larger versions of the images can be viewed here at Flikr. (There are other designs referencing Microsoft’s Zune player, but they don’t have the instant visual recognition factor of the iPod.)
