If I was a CEO and saw how few and far between (as well as toothless) the repercussions have been for Elon Musk, I wouldn’t fear tweeting whatever I wanted either.
If you were a CEO, you'd often be set up for life with some level of financial prudence, and everything else after achieving that level of wealth seems like it'd just be for a lark or some pursuit of satisfaction/happiness.
To be a bit pedantic, there are CEOs of all sorts of organizations, many of which are tiny nonprofits that bring in very little money. You could be a CEO and bring home $60k a year.
