After a very dramatic week of milestones at Twitter, Elon Musk has decided not to join the board of Twitter, the company’s chief executive Parag Agrawal has said.

A few days ago, the Tesla chief was appointed to the board after Musk revealed that he had bought a 9.2 per cent stake in the social media platform.

Over the weekend, Musk suggested a series of changes to Twitter Blue premium subscription, including banning advertisements, slashing subscription price and giving the option to pay in the cryptocurrency dogecoin. He even asked his more than 81m followers whether Twitter is “dying”. “For example, Taylor Swift hasn’t posted anything in 3 months” and “Justin Bieber only posted once this entire year,” Musk has tweeted.

Agrawal has tweeted: “Elon shared that same morning that he will no longer be joining the board.” But the Tesla boss remains Twitter’s largest shareholder and the firm will remain open to his input. Musk’s share in the company is more than four times the 2.25 per cent shareholding of Twitter co-founder Jack Dorsey.

Though Musk had agreed not to buy more than 14.9 per cent of the company, in theory, he can buy Twitter outright. According to the BBC, his decision to reject the offer of a board seat now leaves the door open, if he so wishes, to take an even larger stake in the company.

Last week, Musk started a poll on his Twitter account, asking if the company’s San Francisco headquarters should be converted to a homeless shelter as “no-one shows up (to work there)”. More than 300,000 voted, with 90 per cent answering in the positive.
