The system in iOS is still not enough because the app knows if you declined, so it can keep asking you ad-nauseam until you either accept or until you uninstall the app. For example Facebook's messenger asks for being able to show notifications every time you load the UI. It would have been good if there was a way to lie to the app. For example if it wants access to your contacts, it could get a blank list. Of course, it is much easier to not use such apps in the first place. Uber is not alone in doing this and personally I take it as a signal of how I'll be treated as a customer.
