I'm not clear on what you want? There are two mobile operating systems, do you want some company to make another one? What is stopping them?
Anticompetitive practices are stopping them. That’s the point of these fines. Google controls the predominant non-Chinese marketplace for apps that are compatible with android-based operating systems, and they use it as a hostage to force other device manufacturers to arbitrarily force other google products upon their uses, for the purpose of unfairly expanding their market dominance.
Either way, you're still going to have 2 operating systems: Android and iOS.
