As much as interviewers want to be seen as tough, they have to balance that against people not being willing to appear on their show anymore, depriving them of income and influence.

A not unreasonable position. There are commentators to do that work later on.

I know but it requires some serious acting skills to sit and nod when the person in front of you is promoting themselves as the smarterst person in the world . Add to that that you maybe saw them stumble on the stairs or burn their tongue with some hot coffee a couple of minutes earlier when preparing to start the interview.
