>As an extreme example imagine if Apple tomorrow said that all apps have to pay a 95% cut instead of a 30% cut and all customers have to pay $20/month to use Wifi or internet on their iPhone.
If they did they did this with the app store as used by existing iphones, then that would probably cause them to get in trouble, but if they made a new app store with these policies that was only used by a new model of iphone, then while extreme, I'd think it's within their rights. It's not that long ago that feature phones with limited app selection and internet browsing as a premium feature were a thing.
