Judge orders Apple to approve Fortnite or explain refusal in court. The outcome could reshape how you pay for apps and games forever.

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.
