The court ruling makes it possible for Microsoft to now launch its Xbox mobile store, but it’s clear that the software giant also wants to ensure Apple’s appeal against the ruling isn’t successful. If Microsoft did launch its Xbox mobile store and then Apple won a temporary stay, it may have to pull that store pending the appeal process.

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.
