(Reuters) -News of Tesla Chief Executive Elon Musk taking a board seat at Twitter has some Twitter employees panicking over the future of the social media firm's ability to moderate content, company insiders told Reuters.

Within hours of the surprise disclosure this week that Musk, a self-described "free speech absolutist," acquired enough shares to become the top Twitter shareholder, political conservatives began flooding social media with calls for the return of Donald Trump. The former U.S. president was banned from Facebook and Twitter after the Jan 6. Capitol riot over concerns around incitement of violence.
