One recurring trend in Musk's successes has been mockery. When SpaceX was still a tiny upstart, their ideas of reusable rockets were actively mocked by "experts" in the industry, which proclaimed they'd already long since researched such ideas, and they simply weren't economically viable.
And similarly with Tesla. It's claimed he didn't start Tesla, which is technically true but misleading. He joined when it was 4 guys with some big ideas, but the "real" founders of the company would "leave" before Tesla's first product, The Roadster, hit production. Beyond that, electric cars were largely seen as a "radical" (as in dubious) idea at the time, with the status quo being hybrids which tended to look weird and be poor performing, more serving as a means of virtue signaling environmentalism than anything else.
Basically, it all gets back to Henry Ford. If you ask people what they want, they'd have said faster horses. When an innovator takes over a company, his ideas are going to look dumb to most people, which is why most people are not innovators.
All that said, censoring Substack looks dumb.
