Apple controls much of the advertising in the free ad scheme, but like the Google Market, they also vet their applications, try to keep porn and objectionable material out of the mix, and have rules about what kinds of applications (and app behavior) can be offered. The rules are tested constantly, as developers try to push the boundaries of what Apple and Google Market will accept. As a consumer, you can go outside of Apple's app store, but doing so is at your own risk. And Apple makes it downright difficult. By contrast, Google's Android operating system has a selection to explicitly permit getting applications from sources other than the Google Market. This is how the Amazon AppStore is enabled to become a potential application source for Android apps.
