And then you need Apple to censor your app (since they obviously know better than anyone what people should be allowed to buy).
And even after all that, Apple are using all of these, to kill Adobe (because that's what it's all about, since adobe is a competitor to Apple). Remember, when Aperture was first released, people were much more impressed with Lightroom, and Adobe hasn't lost much traction.
Anyway, Apple are treating developers like crap. Even if this is only a rumor, it is only a matter of time until antitrust trials get underway (for any number of things). In fact, I'm surprised they didn't happen sooner for the iPod's (which surprise surprise, use protocols to limit them to Apple's own software, which doesn't allow foreign music stores to be integrated).
