What about Larry Ellison, CTO of Oracle? Frankly I think Larry Ellison could say any crazy thing he liked, and no one would really care, and he'd stay CTO and chair of Oracle's board. Because C-suite executives get a "free pass" all the time–especially when they combine their C-suite role with a substantial ownership interest in the company (true of both Ellison and Musk). But most C-suite execs, the average person has never heard of them, and so they don't care what they say. Whereas, Musk is a controversial celebrity, so people judge him by rather different standards than the thousands of other near-anonymous CEOs, CTOs and billionaires in the world.
