Apple's just really weird when it comes to the control they exert over devices.
they do it with 'privacy' in mind and what they come up with is usually better than the worst case but it can still be pretty iffy
eg. a few months back when their notarization/entitlement verification system was being discussed
it's all just their vision of computing (which has some merits), hyper-controlled, locked down and "safe" it's not going to change if you're not comfortable with it you really shouldn't be using their products
