They unfortunately I don’t think will ever have the kind of money required to do something like that. While Google doesn’t make tons of money from Android itself. It has immense value. Consider Also that large portions of Android already are open sourced. The main problem being Google play services. They keep moving OS functionality from general purpose open libraries into their proprietary ones to maintain control.
All they really need to do is work on undoing that and giving other groups and equal voice on its future and development. Then there isn’t much the fascist government can do. Not that they won’t try and throw a fit. But they’ll do that regardless. But yes pull out as much from the Google Play services as possible and open it up app store wise. Putting other app stores front and center with their own and giving them equal billing. Like F Droid Etc. Which I already use for all of my apps that aren’t needlessly made proprietary. Google would do this if they were smart. It’s a bit of scorched Earth. But that’s the best kind when it comes to fascists. The administration will work hard to get it sold off to an ally and last thing we need is Russia with control over Android LOL
That’s a good question and something that is not going to be easy to find out. You’d have to figure out who inside Google works on it their hourly pay and how many hours Etc they actually spend on it.
