Those are installed using apple approved app store. Which requires a subscription and payment of 30%. You can give behind security but the truth is they are afraid.

That’s also not true. You don’t have to go through Apple to run a subscription service. You can have people subscribe/buy content outside of the store and let them use it within the store. Netflix, Spotify, Amazon (Kindle, Audible, etc.), AT&T Now, Sling, LinuxAcademy, and countless others make you pay for subscriptions/content outside of the store.
