The Verge reports: “Now that he owns Twitter, Elon Musk has given employees their first ultimatum: Meet his deadline to introduce paid verification on Twitter or pack up and leave. The directive is to change Twitter Blue, the company’s optional, $4.99 a month subscription that unlocks additional features, into a more expensive subscription that also verifies users, according to people familiar with the matter and internal correspondence seen by The Verge. Twitter is currently planning to charge $19.99 for the new Twitter Blue subscription. Under the current plan, verified users would have 90 days to subscribe or lose their blue checkmark.”
