As a strange event, I actually upvoted bitmapbrother, we agreed on something! As he says, MicroG is a hack, and there's no reasonable point where someone is going to take stewardship of Android away from Google. (Other than antimonopoly action.)

There's no point in having Android if you can't run Android apps, and most Android apps users want are now dependent on Google's proprietary libraries (Play Services). So why would you want an Android fork if you aren't going to be able to run Android apps? Might as well go with KaiOS at that point.
