Musk issued his first ultimatum to Twitter employees: the price of the paid service has tripled, and he can't pack up and leave.

Beijing, Oct. 31 (Xinhua) Elon Musk, the new boss of Twitter, has issued his first ultimatum to his employees to launch a new paid authentication service before the deadline, or else they will leave.

Note: Twitter subscription service Twitter Blue will raise prices, according to sources familiar with the matter and Twitter internal communications show that Musk asked to adjust the $4.99-a-month subscription service Twitter Blue to a more expensive subscription service while authenticating users. Twitter plans to charge $19.99 a month for the new Twitter Blue subscription service, but that price is likely to change. Employees working on the project were told on Sunday local time that they must launch the feature by the November 7 deadline or they would be fired.

Musk made it clear in the months before he bought Twitter that he wanted to change the way Twitter authenticates accounts and handles robot accounts. He is also actively seeking to increase subscription revenue to half of the company's total revenue. "the whole certification process is undergoing significant adjustments," he wrote on Twitter on Sunday. " A Twitter spokesman could not be reached for comment.
