Fortnite maker Epic Games has launched the most significant effort yet to advance the legal theory that Apple's iPhone ecosystem has become so “sticky” that it is a distinct software market over which Apple exercises monopoly power.

On Aug 13 Epic filed a lawsuit in federal court after Apple pulled Fortnite from its App Store to punish Epic for implementing a payment mechanism that bypassed Apple’s practice of taking a 30% commission on in-app purchases.
