While I agree that such thing such as “Share your contacts for 500 gems” or “enable location tracking and we’ll give you access to all these cool filters” should not be allowed in the app store, they should not require that only apps from the app store can be used; you should be allowed to freely install your own (by using special menus or whatever). However, I would also have design the system that you can easily fake these data, so even if it does say "share your contacts for 500 gems", they will not know if the data is legitimate or not. (This capability might be useful for testing purposes too, perhaps.)
