What happens when Apple "curates" it such that apps of a political nature are no longer allowed? Or apps that compete with their own?

EDIT: (1) There is a risk that the vast majority of the population (non-geeks), will increasingly rely on the store to get apps, so smaller innovators/FOSS projects will not have the same exposure as others if rejected. (Think the Microsoft antitrust issue with the preinstallation of IE on Windows. People could still get Netscape elsewhere.) (2) This could also be a first step, much like the iPhone/iOS app store, in Apple being the arbiter of all apps that are allowed on Mac OS X.
