What irritates me is that they say that the data is "anonymous" but it is clearly grouped to develop a targeting package to you, so how anonymous can it be when you log into the store from your house every few days.
Saying "here's this guy's address, provide an ad for him" is very different from "send me ads for this area, and I'll show them to people who are near there".
I want to know what's being collected on me, where it's going, and what it's going to be used for. Heck, if anyone has the capability to make this kind of disclosure uncommonly clear and intuitive, it's Apple.
They will probably give you at least as much control as facebook as they will be able to target you by the apps you own. If this is the case then its not that hard to target ads to exactly one person. See here: http://www.gabrielweinberg.com/blog/2010/05/a-fb-ad-targeted...
