I fail to feel outraged by this process. Is "White Fragility" without criticism? Probably not, I think it is a fantastic book, but it scares the bejeebers out of some people and we get instagram drama and articles like this which I interpret as another attempt at purity (trying to outsmart "wokeness").
It is going to take a while for society* to come to grips with this new shift, because we're clearly not going back, but it definitely is rough around the edges, IMHO, because we haven't found the right vocabulary and framing. Unfortunately it is going to require people to sit with feeling uneasy, and that is something most people cannot tolerate.
