And beside those who survive (and provide us with great software), let us spare a thought for the ones who didn't, proof the opensource community can be an evil pit of haters: marcan and AsahiLina.
Both quit for different reasons, but both did it facing extremely unpleasant behaviours.
As a regular Asahi user (m2pro mbp), I literally felt the project slowing down when they quit.
An outcome of that crisis was the buildup of an organised directorial structure, with funding through the "Open Collective" organisation. That's good, and it's full of good people in there. Alyssa is an admin now btw.
Let us wish them all the best (and strength against all evil neckbeards).
