So if Ann's a developer and doesn't want their payment processing, and Bruce is a consumer and doesn't want their curation, then the buyer and seller should be able to dispense with the surcharge if they dispense with the "service." But they can't (without jumping through hoops.) And what's more, if Trusty App Corp. were to come along and set up a 20% cut Trusty App store that could be conveniently installed via an exploit, they would be undoubtedly sued for IP violations, due to the state protecting Apple's exclusive right to Apple IP. This is pure rent-seeking on the part of Apple, and ultimately antitrust laws exist to discourage rent-seeking even more than discouraging monopolies per se.
