Creating an alternative platform could be interesting, though several of these exist already. Twitter remains, by Elon’s own admission, the de facto public town square. Despite its severe censorship, it is still the only major digital public space where anonymous accounts can interact with celebrities, journalists and business titans (including Elon), where world leaders engage in spirited public diplomacy, and where dominant cultural and political narratives incubate and spread.
The most exciting possibility is therefore the most obvious one: Musk should simply buy a controlling stake in Twitter itself.
