Marco Arment, on the recent U2 promotion on iTunes:
The right way for Apple to do a big U2 promotional deal like this would have been to simply make the album free on the iTunes Store for a while and promote the hell out of that.
If you’d like to remove the U2 album from your iTunes account, Apple has published a technical note detailing how to do so.
I’ve turned off the “Show All Music” setting on all of my devices (from within the Settings app, under Music), so I haven’t been annoyed by the existence of the U2 album. I can imagine being very irritated if music I didn’t want started showing up on my iPhone without asking me, though.
Apple screwed up on this, they shouldn’t have pushed music (or anything for that matter) onto people’s devices. Forcing your users to opt-out is always the wrong decision. Especially when many of your users don’t know how to hide music purchases or music stored exclusively in iCloud.
