Who wrote (or said) something about what or which person? Was the indicated talk the target here? Was the person giving the talk the target here? Who was attacked and why?
On the surface that just seemed that the majority of the people contributing to some project (in this case React) are white people which presumably ends up in joining together and dismissing opinions coming from people associated with other groups. Was this the case? Where is the evidence for that? Is / was the discussion completely unrelated to this? Really - I don't get at it all. Maybe a language barrier.
Don't get me wrong - if something like that occurred then a CoC / actions from the project leads must follow, but I just don't see it. Maybe the article is not clear about it.
Thanks for helping me out on this one!
