So if I may rephrase, the issue is that he kind of lost his way as a pure-hearted engineer working for the progress of technology and the good of mankind and started to stray of path with his half-baked political exploits. He is no longer focused on the mission.
I understand the sentiment, and getting as involved into politics as he did was probably a mistake, simply because he is not good at it.
If I may offer a different perspective as to the on-mission part: he realised some years ago that leftism was a grave danger to his plan to make mankind multi-planetary, so he decided he had to get involved, if he wanted to or not. You will probably not agree with this point of view, but perhaps it will help soften the image of him in your own mind.
> that leftism was a grave danger to his plan to make mankind multi-planetary
Yeah, that's just saying "social media addiction" in more words. Also, Star Trek?
I think their statement is useful to contextualise what people consider leftism though. Looking at Musk's actual political actions, it seems like leftism (or at least the part that directly affects him and his companies) is when regulators are allowed to ask Musk to stop doing securities fraud with his social media addiction, and it's not entirely unreasonable for him to consider such enforcement a threat (though maybe not "a grave danger") in case it escalates beyond strongly worded letters. I am, by that metric, a leftist. Possibly a radical far-left communist, even.
