As the owners of the platform Google logically they COULD require all oems to ship open drivers as a condition of using the software. My criticism lays out legitimate concerns as a potential user to a potential user. I don't think it has to have an actionable solution by a third party to be valid. It merely has to connect with objective reality and have a well supported line of reasoning. If you are looking for an actionable item I suggest waiting and seeing how open the platform is and not investing development time or dollars in it if its even less so than android.

As an alternative I suggest you look at actual Linux devices even if they are objectively worse if they are more open.
