I think the other, possibly more meaningful issue, is Apple's control over who can and cannot make an app for their devices. If you put a product in BestBuy, it's understandable that BestBuy would not want you to offer a very cheap upfront price, and then to have all sorts of 'add ons' sold directly to consumer where BestBuy doesn't make any money. It's fair that BestBuy sets terms that they can participate in the follow ons. The limiting factor here, however, is competition. If anyone could make an AppStore for iOS, then the issue of Apple's or BestBuy's 'terms' could be side-stepped. The power imbalance is caused by a lack of competition. If there was competition, app makers would find a place where they were not constrained by in-app purchases, or something along those lines.
