After a five-year legal battle, a judge has forced Apple to allow Epic Games's Fortnite back on the iOS platform.

The problem is that Apple is specifically not allowed to “prohibit” the use of external payment links. It can reject apps, or ban developer accounts, at its own discretion. But if it rejects an app or bans a dev for no reason other than its use of such links, does that amount to a de facto prohibition? Again, that’s debatable.
