App Store external payment: Epic v. Apple case

Judge issues permanent injunction on App Store model in Epic v. Apple case | Engadget

"The judge in the case between Apple and Epic Games has issued a permanent injunction against Apple. The company must allow App Store developers to direct users to other payment systems, which would let them bypass the 30 percent cut of in-app payments that Apple takes.

On every other count, Judge Gonzales Rogers ruled in Apple's favor, determining, among other things, that the App Store doesn't violate antitrust law. She also ruled against Epic in Apple's counterclaim for breach of contract. As such, Epic must pay Apple $3.65 million."
