>Same here -- every app would turn free, and charge to unlock features within using their own payment mechanism. This is trivial to deal with. Apple already has rules on apps, they could go from banning fremium apps, to disallowing apps without a substantial free version to enforcing a reporting API on payments. What they can't do is use their position in one market to force marketshare in another market (payment processors). That's classic anticompetitive behaviour. (Aside, freemium apps have a low reputation, and that's why other stores without that rule aren't overrun with such apps)
