As a counterpoint, the App Store also implicitly encourages an "infinite major versions updates" pricing model vs. minor point release updates = free, major = paid upgrade. In order to do something like that in the App Store, you have to make your next major version listed as a completely separate app ID. Almost no one does this because everyone in the App Store ecosystem expects new version = hit Update All - and the few times I've seen this done, it resulted in nothing but negative App Store reviews. By not providing anything other than a single purchase price, Apple has not just discouraged the upgrade price model - they've discouraged everything but a one-time flat price or admitting to the customers that they're truly a SaaS model (by forcing the developer to do it as an in-app subscription purchase). I prefer this simplicity.
