Musk (and Trump) are really, really good at vocally saying things everyone agrees with to cover the fact they're doing the exact opposite. They're populist champions to such a degree that their supporters (and even the media / independents) can't fathom they don't actually care at all.
Free speech, no wars, anti-corruption in DC, etc. These are all things most people agree with. If some of the stuff Trump/Elon did secretly leaked, people would be going crazy. But they've mastered the art of publicly being hypocrites, to the degree that the average person just genuinely can't wrap their heads around.
Like, how can Elon publish "The Twitter Files" and then literally just do way worst stuff with way less accountability, and have people still believe he's a champion for free speech?
