I was on the phone with Apple once, arguing about why the iOS app I put together at work shouldn't be rejected for running location services all the time. The point the representative at Apple made was that something like that needs to be primarily for the user's benefit, as opposed to it being primarily for the benefit of the people behind the app. I was able to demonstrate that to them, and the app was approved.
Apple is about apps being for the benefit of the user.
