If an iPhone owner wants to use an app that Apple has banned from the App Store, they cannot simply purchase it. Instead they must make the widely disproportionate move of spending many hundreds of dollars on an android phone. In practice almost no one will switch phones just for a single app. Similarly, a resident of a communist country could theoretically leave and buy things elsewhere, but in practice almost no one will because of the high overhead of moving countries.
