Exactly. There is in fact an entire range of thought and emotion between joygasm and "u mad bro."
It's worrying because Elon Musk is 1), an idiot, 2), a liar who absolutely is not a "free speech absolutist" as evidenced by literally his entire life of responding to the speech of people who aren't paying him, 3) still an idiot, because he doesn't or likely pretends not to understand that this particular idea of "free speech" is just "free extremism" and "free misinformation."
The majority of people who voted for one of the candidates in the last US election cited things that weren't true as primary reasons for either their vote or their ideology. These things were spread on social media. And even that wouldn't be so bad if the liars at least wanted good things for society, but oh hey totally unexpected but they're also the people who beat and gas peaceful protestors to get a photo holding a bible like a dirty diaper, or ironically (but unironically) say we should hang people who say mean things about them on the internet.
Musk will probably learn that platforms like Twitter made their decisions for a reason, and then make the same decisions. But I wouldn't be surprised if we have to go through a phase similar to every single WoW expansion, where the devs make the same mistake again so they can write a 30 page blog explaining their wisdom when they fix it (again).
