I feel like even the people who dislike Musk are putting too much stock into the genius supervillain narrative. It's highly unlikely he's slowly executing some pre-thought out plan to shift Twitter far right. He's a naïve socially-inept billionaire manchild who got radicalized by a bunch of alt-right grifters. It's a simple as that. No master plan, no 4d chess, just someone who never underwent any real emotional developed.
