The United States Supreme Court has upheld a ruling from a lower court that says people who purchase apps on the App Store can sue Apple for driving up prices and monopolization of the market.
In the class-action Apple vs. Pepper, four iPhone owners sued Apple, saying that the company had monopolized the market for the apps on its store through a combination of its "walled garden" approach to its apps and by charging a 30% revenue share for every sale. That price, they argued, was then passed onto the user who purchases the app as developers are forced to raise their prices to compensate.
The initial ruling on the antitrust suit said that these users were not able to sue Apple for this as they were the customers of developers, not of Apple, and that developers were Apple's customers. However, the Ninth Circuit Court of Appeals overturned this decision and it was upheld in a 5-4 Supreme Court decision with the majority opinion written by Justice Brett Kavanaugh, joined by Justices Ginsburg, Breyer, Sotomayor, and Kagan.
