Elon strikes me as worse because he likes to think he understands what his engineers know.
Early on in my career I had a name for this. I called it "gamle helter" in Norwegian which roughly translates to "old heroes". An "old hero" is someone who used to be competent in a field, has stopped being competent, doesn't recognize this themselves and is now a nuisance to anyone who actually knows what they are doing, but can't pull rank. One way to become an old hero is typically to end up in management and not practice whatever discipline you think you understand.
To be fair, I highly doubt that Musk was ever a competent software engineer, much less a good engineering manager. He is a PR person. He sells an image that he is a technology person.
What I wanted to say is that if the state of the code is bad, it might make them care a bit more when their own state gets synchronized with that. Not necessarily about the code, but surely about the revenue and the looks.
Now, management being what it is, they of course will try to find a scapegoat. But that’s just part of the game and may be better than burning yourself out by trying to fix their nonsense.
Since you linked Wikipedia, I'll quote it.
