Same here, andymc. It's the major reason why my company had stopped developing for iOS.
From what I just read this morning, though, their new policy will only apply to non-game types of apps (which we don't develop anyway) and there's some disagreement on exactly what "subscription type" apps they're talking about allowing a re-direct from their App Store purchases. Is it only things like Netflix or magazine types of apps? Almost all of our apps/services are subscription based but they're business solutions and not media, social-media, etc. The apps are free but to actually do anything useful you have to subscribe to the service and a lot of the value is in the web portal (many B4J served) where the apps send data for the customer company.
