I think the quote makes a mistake lumping Musk in with the other group, missing that his trolling differs from their pursuit of wealth.
"Where Musk has struggled to keep that constituency happy, it reflects less on his seemingly sincere receptiveness"
The above sentence captures it.
Musk struggling to keep that constituency happy? I think don't think he does or cares. He plays with his toy with happiness a second thought.
Seemingly sincere? Musk seems sincere to this author? I can't imagine how.
The article is spot on about those silicon valley types, but it doesn't see that Musk is not like them. Doesn't make him better or even ok, but he's a different type of jerk.
