The public termination came after Frohnhoefer tweeted evidence suggesting that Musk was “wrong” about his claims that Twitter was running, in the billionaire’s words, “super slow” in various countries. Sources have indicated to CNN that employees in recent days had been very candid in criticism of Musk in the company’s Slack. (CNN has attempted to contact fired employees to confirm.) In addition to the public pushback from employees, some Twitter staff appear to have tried to appeal to Musk and his inner circle privately as they weigh numerous disruptive changes to the platform. The paid subscription service was suspended on Friday with little warning.
