While it is undeniably true that Android, just as any other networked product by Google, is a nightmare with respect to privacy, I hardly believe that Apple doesn't collect any user data. They very likely want to remain the #1 solution for wealthy people who don't want their communications to be bugged, and they're surely much much better than Google in that context, still I don't trust them because their product is even more closed than Android, therefore impossible to audit just as Android.
