I suppose the unfortunate thing is, that isn't his role. He can still do engineering work when he has the time, but me, the SEC, and most other humans understand the CEO of a public company has actual responsibility towards operations. Part of that means, he might not being doing his job great if he works his employees 90 hours a week and pretends they don't exist when he wants to brag on the radio. Being kind and generous with well deserved praise costs nothing and actually benefits both the company and the humans making the company work.
