The fact that Mozilla seems to rile opponents of social justice makes me think of donating to them.
Agreed. They annoy all the types of people that I'd much rather not work with, and I honestly believe that Mozilla is better off without them. I don't care how irreplaceable they think they are. Nobody's irreplaceable, and there is plenty of talent and skill out there that isn't associated with such noxious people.
Mozilla's hardly alone here. Plenty of other open source communities are like that. It's just they get the most flak, for some reason.
No organization can simultaneously satisfy SJW strictures and be good at its original mission. What's happened to Mozilla is very sad, because its nominal mission is one I believe in too.
