To be honest, it sounds like pretty melodramatic bickering (no offense STN). Hell, I don't see it as intrusive at all; if iTunes keeps sending free music to my device, that's great. If you don't like it, then just delete it. I don't care if it's Justin fucking Bieber.
It seems as though it's a gut reaction among folks to perceive corporate intrusion as a basic violation of their privacy rights. I think that's absurd. You say it's a "bonehead move" as though they violated some sort of basic principle; but they didn't, and I bet that a lot of people don't give a flying fuck that a U2 album popped up in their music feeds.
