So are you suggesting that, since it's been a while since Apple created the App Store, now control of it / what it provides should be forcibly taken away from them? If you own a house, and you've lived there a long time, at some point should the government be able to decide that you've been the exclusive occupant long enough and now they're going to authorize other people to come live in your house? How does the passage of time erode ownership?I completely agree that Apple deserves credit for having created this ecosystem. But it's been a while now. How many years can Apple continue to extract a rent from their position? They are currently not inventing any new race anymore, they're certainly not providing all the gear (or do developers NOT have to buy expensive macbooks to use Xcode now?), and are they giving iPhones away for free or are they selling them? so they might have built the racetrack but once they sell it they don't technically own it anymore...
I think Apple probably ought to lower the percentages they're charging. But that's personal opinion, not a command to Apple. They built their system, and it seems to be enormously popular with a lot of people. There are others who are unhappy with the deal that Apple offers. They can go use the widely available alternatives. That would be primarily Android. If there is a huge untapped market that hates both Android and Apple, then that's a golden opportunity for some new company to come along and build their own alternative. But, "some people don't like Apple's deal" is not a reason for having the government take away something Apple built, from Apple.
