Our recent experience seems to confirm what the author in TFA is saying. We do a lot of business on a contract basis for a local non-profit. They've had several chief executives in the last few years. The best one was clearly an introvert and basically left her people to do their work. The worst, and current one, is a flaming extrovert. She insists on being the center of attention at every meeting and doesn't take well to sharing the spotlight with others. The only thing that's allowed us to keep working with this organization is that the board has given us permission to set up what amounts to a satellite operation off site so we don't have to deal with the "manager".
