As I’ve said to others this isn’t the same. Microsoft aren’t selling an app, a subscription or a game and bemoaning the 30% fee. They’re trying to put a free app on iOS, a client for their streaming service, an app with no in app purchases on iOS, something for their existing subscribers to use, and Apple won’t let them. Apple’s rules say they have to include the ability to subscribe to the service within the App, and Apple can take a 30% cut of that fee. That’s the issue, not that they take a 30% cut, but that they’re being forced to sell the subscriptions that Apple will take 30% from in the first place.
