How much "profit" does the app store need to pay back to all the api development that powers the apps under the hood?
Similar to the amazon dont make a profit for a decade by dumping it into growth, Apple can dump all their app store "profit" into developing new api's that apps can access, such as ai tools etc.
Apple is quite large, so I suspect they don’t exactly use the same strategy as Amazon did in its early days. It also wouldn’t be profit, because that would be an expense they would keep track of.
