Android is open source platform, you don't need Google for Android.
Android gives you a base system so that you don't have to reinvent the wheel while creating an operating system. All phone manufacturers build on Android to create OS for their mobile.
Googles monopoly is because a lot of things we benifit from Android is cross compatibility of devices from different companies which is facilitated by Google - Play Store, Etc.
This monopoly of Google is not forced but domination of it in Android space since the very beginning.
Anyone can create an OS without Google services but it would be very less useful compared to Android with Google services, because of lack of compatibility.
Any alternative for F1 pls.
I know it's not on cable but still. :)
