In order to become profitable, the primary objective of Twitter should be to create a medium that is attractive to advertisers.
This is not inherently a technical problem. You can't solve this by firing a bunch of people and threatening the rest. Inviting extremists and goof balls to the stage for some politically oriented "free speech" won't do it either.
For the first time in his business career, "success" is not about doing what Musk wants and stroking his ego. And he is not handling it well.
Bottom line: Advertising is not the ideal business for a "free speech absolutist". Watching Musk with all his wealth slowly and painfully come to this simple realization is actually kinda entertaining ... or maybe I'm just as disturbed and egotistical as he is.
