That is quite the assumption to make, how do you know why they think Musk is not to be trusted? There are many of us who have been saying this for years. And you have to admit, even for him his actions in the last year have been egregious. Also, just because you do not see people complaining about the other 1M CEOs doesn't mean they don't exist.

Musk isn't untrustworthy just for being vocal. He has too much power and has shown he'll break rules or even the law when it suits him. Someone who is inherently political and wields this much influence without accountability should never be trusted.

Being vocal is one thing but constantly attacking someone on x while spreading misinformation or straight up lies doesn't add to ones credibility either.
