Musk is almost cartoonish embodiment of "entrepreneurial spirit", with his unremarkable background, eccentricities, outlier success and disregard for unions. In other words, he is clicking all the wrong buttons for political left, leading them on the trail of hunting for personal flaws (which he certainly has) and focused nitpicking.

So yes, these people would rather see SpaceX or Tesla never happening, as a "bad" person doing good deeds invalidates much of their worldview.
