I think this is quite perceptive. Musk is a narcissist, and the driving motivators of narcissists are a bottomless need for praise and attention and contempt for others.

Musk is famous for being contemptuous of his employees, and he's starting to show more and more contempt for Rest of World. Cybertruck and X both reek of it.

Everyone here is assuming Musk is rational and SpaceX and Starlink will continue to develop rationally.

I don't think they will. He appears to be becoming more and more unhinged, and that's going to have negative effects on his fledgling empire.
