This type of response is exemplary of totally misunderstanding the problem.
The problem isn't the app store, and sweat-of-the-brow has nothing to do with anything here.
The problem is twofold: (1) the App Store is half of a very powerful duopoly that must be used to distribute mobile software, there is no way around it, no choice, and (2) Apple competed on their own App Store with third parties, but Apple bends the rules such that they have a distinct advantage over third parties on the App Store. On their own, (1) or (2) aren't problems. It's only a problem when you get (1) and (2) together at the same time. Thus, Apple uses their platform (App Store) to unfairly advantage their other business (Apple Music).
It's akin to Rockefeller: He bought the railroad companies so that only he would control distribution of oil. At the time, rail was pretty much the only way to distribute oil. His oil was then distributed nearly for free, while he charged competing oil companies a huge premium to distribute. The other companies couldn't compete, because their oil was always more expensive than his due to how much he charged them for distribution. Thus, he used his monopoly platform (railroads) to unfairly advantage his other business (oil).
A lot of flies in your sour tears ointment. Apple only has 20-30% of the market, so it has no control of the wider market.
Rockefeller did not buy up the railroads, he had a monopoly on Oil Refineries (90%) not rail lines. He worked out sweetheart deals with rail lines because he was such a large customer.
If Rockefeller only had 20-30% of Oil refineries he never would have been considered a monopolist, and Standard Oil would never have been broken up.
Nice attempt to tie things together with a bunch of made up alternative "facts".
