This was never how the software industry worked, literally ever. Do you remember buying software off of a shelf in a retail store? The store took 50%, creating the media cost another 20% or so.
Do you remember when you bought a video game for a game console, ever? Royalties and license fees are paid to the platform holder.
How about a CD or Blu-ray? Guess who was making money off of every one of those?
You don't even understand the point of all this. Your comment confuses how the software industry evolved with who controlled the industry (which was no one). So your comment actually proves the anti-trust case agains Apple.
Here's why:
IBM created the original IBM PC. If IBM controlled the software for its platform all those stores would have been IBM "App Stores" and we all would still be shopping there. IBM probably had the money to try this at the time so it's not as far fetched as you might think...
And of course (you'll love this one) if Apple opened such physical stores to compete with IBM at the time they never would have survived.
The only silver lining would be Microsoft also would have never survived.
