"Could" is doing a lot of heavy lifting there. My point is AWS and Apple's App Store are very different business models. Once is about providing compute resource while the other is about providing a single pane of glass for software purchases.

Sure, the App Store "could" follow AWS's pricing model, but it makes more sense for it not to given the App Store is more analogous to a shop like eBay or even a physical store like Argos than it is a cloud computing data centre.

This is why I said the AWS/App Store comparison isn't apt.
