I don’t think they were expressing concern, just the fact.

I read it as a damning indictment against anti-“DEI” fanatics that they’re on the wrong side of history when they push the envelope too far in the direction of “merit-based hiring”, as if DEI was something relatively-recently concocted.

Laughably, in the days before “DEI”, “merit-based hiring” usually equated to “good old boys club”. Based on the industries in which I’ve been involved, it’s still very much “good old boys club”, despite best efforts for DEI to try to make things more merit-based.
