To me, the value Apple provides is a simple in-app flow to make a purchase. That's worth something. Getting kicked out of an app and having to type credit card info into a browser would suck. But is it worth a 30% markup on each transaction? Well, disclose the fee to users, give them an alternative (shittier) option to pay, and find out. I think an actual free market with forced transparency would settle on transaction fees an order of magnitude less (i.e. closer to 2% or 3%), similar to Visa and MasterCard.
