Regarding #1, no one is stopping any app developer from charging 30% more than what they currently do and seeing if consumers will stay with them. Apple already has my data... they have time and time again proven to be reasonable stewards of that data. I do not want to play a guessing game with 40 other developers to see if they all follow that. I've been burned too many times. Regarding #2, we didn't depend on the mercy of corporates in the PC world. I saw firsthand how annoying it is to debug my parent's computer repeatedly when random apps get installed or terms of service overstep. For less tech aware consumers this is almost certainly a win in terms of privacy and general experience.
