Now the user has to manage their privacy for a bunch of apps through Google's central server instead of the app itself, and the app now needs to talk to google as well - seems like kind of a drag to me. Extra moving part for dev, and for user kind of like having settings for a game in your system preferences, sure it works but it's a bit odd. And the cell tower problem too, which I didn't know about.
