Do iOS users realize how much they're paying Apple? I feel like if, every time they bought something, users got a receipt with a line item showing that 30% of the money was going to Apple and not to the company they thought they were buying from, a lot of them would jump ship to Android.

Apple makes it against the rules to tell users about the 30% tax.

But then their bubble would be a pukey green color, and not a nice blue color, and that's scary for a lot of them.
