This is indeed concerning and could get out of control very quickly. If they really have been blocked for that post, it’s a violation of the key policies of the Godot Foundation in my opinion. (See section 11)
I’ve been CM for projects of similar and bigger size in the past, and they always had one important guideline in common: stay out of politics. Everytime this wasn’t followed we burned our fingers.
Sure, one can try it anyways, but I doubt that there is a way to handle that many people with different opinions and political orientations, at least not without burning out at least 6 CMs per year.
