It re-enforces the idea that he is a "genius" who is playing "4D Chess" and that he "has a plan" and not that he's a fucking drug addled freak who is making decisions based on his emotional state at the time.
There was no plan, there's never a plan. Rich people just play this game where, because they have enough money to insulate themselves from their bad decisions, they pretend that "this was always their plan."
Anyone who thinks spending 44 billion dollars on shutting up a teenager constitutes a "genius plan" is already fully on-board the Musk cult. I don't think there's really much reinforcement happening.
I agree we shouldn't pretend he's anything less than a dumb asshole who got caught with his pants down.
I dunno man. A teenager baiting a billionaire into spending a significant amount of his fortune to shut him up sounds like the most successful troll in history to me.
