Jobs was smart enough to stay away from the spotlight and social media. Musk, on the other hand, is extremely addicted to it.
There is something else going on, however. He is known to partake in uppers and downers like Ketamine. Extreme wealth, insecurity, obsession with public opition, and drugs are a really nasty cocktail.
Elon is simply making abundantly clear that he doesn't care what advertisers feel. If they want to stay, they can stay, and if they don't they can leave. And he's fine with that. That is a reasonable message to communicate.
He looks, sounds, and acts unwell. But even that doesn't really excuse his behavior, just explains it possibly.
He is fine, his values simply don't align with most peoples'. He is acting quite consistently with his stance on how he wants to run X (eg profit is not the primary goal.)
