The impact of the OEM deals can not be understated, and actually account for Android not being dominant in TV or IoT because Google don't quite understand that other companies aren't idiots and they didn't want a replay of the phone situation. For instance, for a long time if you wanted to make a device with the Play Store on you could not make any Android device which did not have the Play Store, even as a third party for someone else. If you do that while making billions in platform fees don't be surprised when everyone else thinks building their own app stack on top of vanilla embedded Linux is a better idea. Of course often the OEM intentions are far from honest, but the deliberate result of Google's antics is to prevent the emergence of any honest actor trying to produce an Android device which does not serve the ad tech beast.
