"Elon’s narrative is that he’ll bring “free speech” to Twitter. What exactly does he want to say/do on the network that he hasn’t said/done already"

Maybe it's not about what _he_ wants to say. Maybe he perceives that social media is broken - which it is.

Maybe his vision, which he has not articulated yet , is something that people have not yet imagined.

So many people are tearing him down before they even hear what he proposes.

I call that toxic.

Update, 2025–Jan-9: Time has passed since my response above, and it is increasingly clear what Musk wants. I am quite disappointed.
