Push notifications are both wonderful and the bane of many of our existences, and keeping them under control can be a full-time job in itself. But while iPhone notification overload is very real, that isn't the biggest issue that you need to consider the next time you tell an app that yes, sure, it can send you push notifications whenever it likes — because those notifications can be used to spy on you.
It's something that has been pondered before, but now we know it for sure after Apple confirmed as much. It also confirmed that it was the subject of a gagging order from the federal government that prevented it from sharing information about any requests relating to push notification data, but that order has now lapsed after a letter to the Department of Justice brought the situation to the fore.
