Could that happen? No. A massive amount of android development comes from employees paid by google to do it. What amount of resources should be siphoned away from linux/gnu stuff to support android developers? None. Is it possible though? No. Android is a proprietary binary blob core (idr if kernel is the right term) with a bunch of open source stuff wrapped around it. For gnu, that part would have to be rewritten and that’s too big a job to take on. Should it happen? Again, no. There are already plenty of alternatives to google branded android. Just use those. Even if you were to wave a wand and make the android custodians according to your will, play services, the thing google is restricting, is still googles thing.
