I think it's relatively well known that heads of people/whatever fancy name HR peeps come up with for themselves are generally sociopathic scumbags, so it's not surprising to me that this was the case.
Actually we have lots of data on sociopath and narcissistic tendencies in management. Management consistently scores higher in these negative personality traits.
Have you met any of these people? They're quite normal people like you and I. They've climbed the ranks in some cases by spending 20+ years at the same company. The discussions I attended were HR leaders in attendance only aside from myself. I was just popping into breakout rooms and observing. I left with the impression that the HR leaders are genuinely interested in improving the workplace experience. A central topic for instance was "How can I convince my CEO / board that we should allow hybrid / fully remote?". If they were sociopathic scumbags I would instead expect "How can we force employees to come back to the office" discussions.
