Agree. Here is a different take.
Unity was created by a corporation with massive resources. It was abandoned when that corporation changed its priorities. If proprietary, Unity would have died long ago.
Due to the efforts of a 10 year old volunteer, it was fully modernized and became quite popular again, offered in many distros. The lifetime of Unity as a project has already been extended by years. A 10’tear old kid. That is the power of Open Source.
The main contributor is not able to work on Unity right now. Others can take up the effort, because it is Open Source. That includes any user or group of users that live or rely on it. The opportunity is available to anyone.
Absolute worst case, the world already got more Unity than it would have. And it could be revived at any time.
AerynOS seems to be ok though. Tune Morling (erno) seems to be very active in their repos and he is the current project lead.
I mean, we will see. I guess it is still in Alpha.
