How's Rhapsody affected, if they don't offer in-app purchases??
quote:
"Today, Rhapsody subscriptions are available for purchase exclusively via Rhapsody.com"
(You could possibly have a separate offer with iOS availability at a price that compensates for Apple's cut, which means you would get Apple's cut from everyone buying iOS availability outside the app.)
But I still think the idea is to avoid what would be perceived as an Apple tax when buying subscriptions in-app.
They might back down from this like they did for the dev license changes, but this habit of always changing the rules in the middle of the game regardless of who gets hit is really getting old.
