There's already an open, less invasive forks of Android - LineageOS being the biggest of them. It's easy for a company to be formed around them and continue development. Cyanogen was one of them.
And you wouldn't use it, because it would probably just die.
Like Ubuntu, Firefox, Raspberry Pi, Wikipedia, Bitcoin...
I think the chance that a commercial company is going to spin off into a community-driven non-profit is pretty low. Or at least their chance of success is going to be low. The examples you gave built up their communities over time.
- Ubuntu: Subsidized by Mark Shuttleworths personal fortune.
- Firefox: Most all revenue is in the form of indulgences from Google.
- RaspPi: Broadcom sockpuppet.
- Wikipedia: OK, can't argue with this one.
- Bitcoin: Money laundering, pyramid schemes and currency speculation can hardly be called an 'open source project' IMO.
I agree with Bitcoin being used for shady stuff, but could you explain how it's used for money laundering? My understanding of money laundering is a process of making shady money look less shady. Putting it through anything in Bitcoin will make it look more shady, won't it?
