What we have noticed is that Netflix and Spotify handle their subscriptions outside of the app to avoid the 30% charge. With this though, there are limitations such as not being allowed to explicitly direct your users out of app to make payments. There are a lot of holes they are jumping through to avoid the 30%.
Unfortunately, there aren't holes and that's the problem. If you can charge for your product outside of the AppStore we wouldn't have this conversation in the first place.
Apple forbid charging the customers outside of the AppStore and you have to sign up and charge through the AppStore.
HEY is already trying to do this, but Apple changed their policy recently that if you offer a subscription you MUST allow for users to sign up through your iOS app which means paying the fee.
Also it seems to be a per case situation. They won't force Netflix or Spotify to change it, but they sure will try it on emerging apps that don't have the kind of resources those other behemoths have.
