I'm amazed that anybody gives a shit about this. It's a line on a résumé about a degree he earned 33 years ago. If he was 2 years out of college then lying about his degree would be material to his qualifications and compensation. After 30 years, what possible difference does it make? He is clearly qualified.
You missed the part where the lie is also on SEC filings. This exposes the entire company to liability. In this case it also gave a bullet to one faction during a war for the board.
These are not the situations you want a CEO creating, no matter how they do it. That it's all from a relatively petty lie makes it all the more aggravating I'm sure.
I think the breach of ethics should be a big deal. We've grown too used to the idea that if you profit it's ok to commit some small deceptions. It's an acceptance that harms us all.
Well lying about something that can be so easily checked is certainly silly - but lying convincingly to customers shareholders, regulators and investors is surely the whole point of being a CEO?
Otherwise we would just let the engineers run the company!
