I was hinting at the possibility of having a platform where there is no central app store to even allow such "dynamics" to unfold. > I'm not sure what you want to say here That the Apple platform with the store model has significant disadvantages.
Ok, but do we agree that Epic getting what they want would result in a more open platform than what we currently have? Because the alternative to what Epic want (so the current situation) isn't a completely open platform but one where Apple is the only boss and can do almost whatever they want. Having more bosses in competition for parts of the market is an improvement toward a more open system.
I think Epic getting what they want will slowly hollow out the available market for smaller indie developers who can't compete with with the scale of the big boys. Insofar as Apple's app store falls short, it's often in the various ways it fails at providing a truly even playing field between Joe Random and the Amazons and Epics of the world. Take the Apple intermediation out of it and the big stores can bring the strength of their reputations and the scale of their logistical capabilities to bear in ways that will make it much more difficult for small, independent developers to thrive.
You can see it in comparing the iOS app economy to the Android one. Even though the vast majority of app installs in Android come through the Play store, the more lax standards and availability of sideloading seems to make people much less trustful of anything they get and, consequently, much less likely to spend any money.
