Explained: Why does Apple run its App Store with an iron hand?

Over the past week or so, Apple has eased some longstanding restrictions that helped make its App Store into a big moneymaker for the company. The company has long required app developers to pay high commissions to Apple on the sales of paid apps as well as purchases of subscriptions or digital items inside their apps.

Apple is facing some significant pressure to open up the App Store further. A federal judge is soon expected to return a verdict in an antitrust lawsuit filed by Epic Games, the maker of Fortnite, that seeks to strike down much of Apple’s commission system.
