Tesla and SpaceX CEO Elon Musk has only been “Chief Twit” of Twitter since Thursday night, but he’s already fired four top executives and dissolved the company’s board.

Musk had repeatedly tried to pull out of his $44-billion US deal to acquire Twitter since April, leading to legal action from the company. Now, as Musk and his investors take private ownership of the company, his messages about free speech and lighter moderation have been joined by an assurance to advertisers that Twitter won’t become a “free-for-all hellscape.”

Today on Front Burner, Washington Post tech analysis writer Will Oremus details the chaos unfolding inside Twitter as Musk begins his reign, and discusses what the ownership of social media by billionaires such as Musk could mean for our online future.
