True, but "usability" isn't relevant to the point I was making about there being an uncrackable scheme. It's very much a choice of the company how crackable a given DRM scheme is, and that depends on how much effort and processing hardware they're prepared to throw at it.

(The most well known example is CSS - one of the reasons it's weak is that it's designed to work with a very limited level of processing hardware)

Half the time, the "encryption" is nominal and designed to invoke the DMCA/EUCD protections rather than to provide useful protection.
