A corner of this page discusses the current proliferation of Digital Rights Management techniques:
ZDNet Executive Editor David Berlind suggests that CRAP or Content, Restriction, Annulment, and Protection, is a catchier phrase than DRM – Digital Rights Management. Why does he think this technology is crap? Once you’ve bought music or other content to play on one device, it won’t play on any other device because of the proprietary layer of CRAP.
