This is not so much a problem with Musk himself, but with the massive media consolidation we've seen over the past 40 years in America.
With the recently approved mega-mergers its becoming even more consolidated and more restrictive of free speech.
Musk has quite a collection of conspiracy theories rattling around in his head, ranging from great replacement, anti-vaccine, pizzagate, Paul Pelosi, to woke mind virus. I'd be more inclined to blame social media problems on consolidation if it weren't for all that craziness.
