If Apple really cared about privacy&security, they wouldn't do only a milquetoast appeasement like "ban apps who are not transparent about the data they're sending and to whom" (which is arguably how we got into this out-of-control industry sociopathy in the first place, with "self-regulation" and "privacy policies"), but Apple could even kill off most all surveillance possibilities in apps.

Imagine if using an app on your iPhone was regarded as more safe than visiting a Web page produced by the same organization, because Apple protected you more than Web standards do. It's a definite technical possibility, and I suppose it might make business sense for Apple.
