I am honestly curious how they are going to prevent pirated music from appearing unless by "ripped from CD" they ripped by iTunes from CD. But they mention support songs purchased elsewhere in their blurb.
This is all just a guess, but... You aren't seeing this the right way. That money? Part of that is going to the labels. That pirate stuff you are adding? Apple will keep track of it, and the labels will get a cut. So yes, the labels know people are going to upload pirate music. At least now, they get some money from it.
which is a pretty progressive decision by music companies. it's like they're accepting that people will pirate music no matter what drm scheme or lawsuit wave they throw out there, so they're trying to find a way to live profitably with it.
Maybe they just don't give a shit.
