There are some extra levels to this. Imagine a country where there is only one supermarket chain allowed. In that case there is no competition and no choice for consumers.

Before you should people should simply switch phones: you can switch phones, but you can't take the apps you bought with you. And even if you switch: there's only one real alternative: Android. If Apple is allowed their 30% cut on literally everythig, why wouldn't Google do the same?

This way you end up with only 2 App stores, 2 Music and 2 Movie streaming services.

I believe Google does take a cut on literally everything!

We do have only two app stores. Apple and Google just haven't managed to kill all the competing Music & Movie services. They'd love to!

Google doesn't require all app installs to run through the play store. In fact, the OS allows for other app stores to automatically install and update apps. The Play Store may be the only option preinstalled on devices, but anyone can download and install third party apps, and if you're rooted or writing a custom rom you can create/use your own app store. See the fdroid privileged extension for an example of an alternate app store that allows background installs similar to the play store. Alternate app stores in general include the Amazon app store for Android.
