I'm just wondering how this type of thing effects businesses that have an external presence, but also have an app just to make things nicer for apple users... Does Netflix have to pay %30 of their subscription fee if someone downloads the netflix app? I highly doubt that. I'm genuinely curious because I know nothing about the apple ecosystem. I don't own any apple devices, yet I inherited an app that was removed from the app store. A bunch of my customers want it back but I haven't had much success yet.
