There is a crucial element of that form of criticism, which is that it is played like a game: There is a definite time and place, a magic circle, and when it's over everything is "reset" and you just have a project artifact and happy workers. Compare with a boss walking up on the floor and bellowing, "so, why is it late???" Now the whole office is cued in to maneuver and deflect blame, not just that one time but throughout the day, every day, until they leave the job entirely. Really good leadership understands how to maintain the atmosphere for the situation. They can turn up the heat but do so judiciously. They have to do it with care precisely because the individuals tend to be a "bag of emotions", easily swung off track with careless dialogue. The Reddit thread is cautionary towards a neutral business situation where the goals are simply to maintain trust, gather basic information, and assign tasks and plans. Confrontation in that instance is quite destructive.
