This is bullshit, troll. Apple's providing one-click access to customers with credit cards who actually buy things, and lots of them. The idea that they are simply providing payment services and nothing more is bogus.
Or they could just raise the price of the subscription by a couple bucs too. Not saying they should or will, but Apple doesn't dictate what developers and publishers charge, only that they can't undercut Apple and there is a 30% fee.
