Since Windows was considered a monopoly the government stepped in and prevented Microsoft from bundling too much or restricting access to the platform. In a way, Apple should be grateful to Android for keeping the government at bay.
A market share without profit is a useless metric Apple has nearly twice the app revenue Google is no where near a monopoly. Billions of cheap throw away devices matter very little. Apple isn't anywhere near a monopoly either.
That's irrelevant in our discussion. From a consumer or government point of view the revenue of each company doesn't matter. There's plenty of competition and consumers have choice.
