Seems like sideloaded apps will require notorisation from Apple and some form of automated security/privacy scanning (plus a system for authorising alt stores to do the same).

Payment fees for App Store apps seem to be affected in section 9(c) - I have trouble parsing it but it seem to eliminate any fee difference between purchasing physical goods through an app (currently 0% fee) and digital goods (currently 30% fee). There's a carve out for "reasonable costs" for hosting and distributing the digital goods - this could be sensible in certain scenarios (like Netflix asking Apple to a free CDN for them).

We'll see how much malicious compliance the above produces. Otherwise I'm feeling like a happy Aussie today :)
