> In the end I don't think there's anything privacy-conscious app developers can do other than eschew external services as much as possible, clearly inform users when external services are used, and push for stronger regulation (from phone / OS manufacturers and the government) about data privacy. This is the crux of it here. In particular, we seriously need regulations making the things Apple is pushing required by law, not something a company with its own vested interests pushes. Particularly since as many point out whenever this is discussed, there is a bit of opacity with regards to Apple's own apps.
