On Friday Septemeber 10th, 2021, it was ruled that Apple had violated California's Unfair Competition Law by forcing developers (in this case, Epic specifically with Fortnite) to use Apple's payment systems on the App Store where Apple extracts a 30% commission on every in-app purchase in the process. It was not ruled however that Apple holds a monopoly as the suit was also arguing.
To get around Apple taking that 30% cut, Epic had encouraged iOS players to buy the game's digital currency, known as V-Bucks, directly from Epic, as opposed to through Apple's in-app purchase system. To sweeten the deal, Epic offered a discount to those who bought V-Bucks directly. Apple saw this as a gross violation of its contract with Epic and an attempt to undercut a key revenue stream. The iPhone maker booted Fortnite from the App store, and Epic immediately filed what appeared to be a largely premeditated lawsuit. Epic is not seeking monetary compensation but rather for Apple to change it's behavior on this manner. Apple is expected to appeal.
