My guess would be that they wanted to stop this sort of thing before it becomes a real problem. There have been numerous examples of this kind of "sjw" behaviour influencing and even targeting big open source projects, and people become afraid of it (Sarah Sharp is the only name I can remember at the moment from such an incident). I don't know the people involved though.
