A federal judge ordered Apple to stop levying commissions on off-app purchases, opening the door for developers to earn more revenue.

The ruling was a stinging defeat for Apple in a long-running antitrust case brought by Epic Games, the maker of Fortnite, on behalf of app developers.

Elsewhere in the filing, the judge says that an Apple executive lied under oath when talking about forcing devs to pay a 27 percent fee for outside app purchases and wrote that Apple CEO Tim Cook “chose poorly” when listening to execs at the company who convinced him to ignore the injunction.
