I heard the same for Android and I was pretty supportive of the sentiment until I listened to the Android Faithful podcast episode discussing it...
If Google doesn't develop Android, nobody will. Whoever buys Android, we don't know if they will maintain the AOSP. Android has been an equal parts rollercoaster of good and bad ideas thanks to Google, but it has had someone do that...
Maybe LineageOS could take over, but that's just insane wishful thinking.
Fair point. I don't think I thought of this lol.
