Android is commercially licensed software. Android AOSP is free, but Android bundled together with the Play store and all the Google apps is very definitely not free.
You keep repeating this, yet all the public knowledge on this subject (leaked docs) suggests that Google apps are free as in beer. Not only are they free, but OEMs are willing to jump hoops (contract with Google) get the $0 Google apps. Do you have any sources that say Google sells it's apps to OEMs?
So OEMs pay Google for contracts and the only reason to get these contracts is to get access to the apps, but the apps are free? Sounds like paying Google for the apps.
