I'm still angry about that XCP digital rights management technology bundled by Sony BMG on 52 of its audio CD albums. According to Gartner (not Mike Gartner, but the analyst firm), it can be defeated by applying a piece of Scotch tape to the outer edge of the disk.
This reminds me of the way one gets around Sony BMG's other anticopying technology from SunnComm Technologie. You simply hold down the shift key. Pure brilliance.
DRM doesn't work. It just pisses off the consumer and drives people to piracy.
