It's nice to see Apple's protecting its IP up front as opposed to waiting to sue random 16 & 60 year olds later.

Playfair and QTFairUse both provided rough applications to accomplish the task of stripping iTunes Digital Rights Management. Playfair was originally hosted at Sourceforge, but was reportedly shut down at Apple's request.

Sarovar was the next home for Playfair, but was also quickly removed at the request of Apple. From the cease and desist letter...

Sometimes companies play IP suits along the lines of an extra revenue stream rather than something they actually want to keep safe/their property. Even if you hate IP laws, I hope you approve of the way Apple uses them (at least wrt AAC; it would appear that they've been awfully heavy handed to a few URL owners).
