Android exits, it's relatively open. I can download an APK and easily install it on my device (unless this changed since I last did this).
Apple is a walled garden. That's both a gift and a curse. I see a lot more spammy low-quality apps on Android, but I also have more choice. I prefer Android for mobile and Mac for desktop.
As an aside, any time I've seen the state intervene in affairs like this it has made my experience as a user worse. I remember something about Google can no longer "favor" their services. So for instance, if I search for an address, it can't show me Google maps because it theoretically harms all the fledgling map companies. But now it's just more clicks for me. I don't care about competition, I care about the best product. If I search for an address I want google maps. If I search for a video, show me YouTube. And if Google fails to deliver the best product, I'll switch.
It's no different than going to a restaurant and them serving only Pepsi products.
