It's one of those sad cases where someone "doing the right thing" opens doors for the bad guys. I remember Google having a page that "educated" about the potential pitfalls of having data locked up in Facebook (on the OAuth approval page). Maybe they will do the same thing here?

Thing is: for technical people like us it's a no-brainer, stay the hell away. This kind of thing is going to get a whole bunch of Aunt Tillys locked up in Apple. From that perspective the one option is clearly more "evil" as it preys on ignorance.
