dream on - he was for DRM when he had a virtual monopoly, now he is losing his monopoly so he has become anti. Dig deeper and you will see.
Whatever be the reason, the fact that he admit's DRM has not lived up to its promise, and the fact that it has failed IS significant. In fact its an indirect slap on the faces of record label's and Apple own policy of agreeing with them. In fact i would kind of it as an encouragement to apply the anti-DRM campaign to the record label's in a more stronger manner :-)
