This is not a new thing. Patrick Lencioni made a very good job in his "Five Dysfunctions of a Team" (2002), where he explained clearly why the "star developer" sometimes needs to be fired to boost net team productivity as a whole. What's new here is the benchmark for "what counts as an asshole". If you need to watch every single word in fear of giving anyone the opportunity to cry 'offense' and invoke a CoC panel on you, that's when all trust in the room goes out the window, and when you really start flushing productivity down the drain. So, not a net positive in my view.
