That's what you get when you use walled garden system. One huge single point of failure. Which always can be efficiently attacked by a resourceful adversary. I get the use case where you need apps "just work" and don't step one step out of the walled garden. HK use case is obviously not that - they should not be using any Apple mobile technology, it's all one huge single point of failure.
