His actions are actively doing the opposite: he is causing his company to lose money.

At Twitter? Sure, but so were the previous guy’s. It’s not actually clear that a social media company can generate revenue at all.

I agree it seems pretty unlikely that Musk is going to turn it around but that’s because the outcome is probably impossible - it’s not possible for Twitter to make money.

Tesla and SpaceX, his other companies, are making money. If you’re on the board of those then there’s no reason to wonder if Musk is causing the company to lose money because you can just look at revenues and see that he’s not.
