Elon Musk has become Twitter’s new owner, firing top executives he had accused of misleading him and providing little clarity over how he will achieve the lofty ambitions he has outlined for the influential social media platform.

The chief executive of electric car maker Tesla Inc has said he wants to "defeat" spam bots on Twitter, make the algorithms that determine how content is presented to its users publicly available, and prevent the platform from becoming an echo chamber for hate and division, even as he limits censorship.

Yet Musk has not offered details on how he will achieve all this and who will run the company. He has said he plans to cut jobs, leaving Twitter’s approximately 7,500 employees fretting about their future. He also said on Thursday he did not buy Twitter to make more money but "to try to help humanity, whom I love".

Musk terminated Twitter chief executive Parag Agrawal, chief financial officer Ned Segal and legal affairs and policy chief Vijaya Gadde, according to people familiar with the matter. He had accused them of misleading him and Twitter investors over the number of fake accounts on the social media platform.

Agrawal and Segal were in Twitter’s San Francisco headquarters when the deal closed and were escorted out, the sources added.

Twitter, Musk and the executives did not immediately respond to requests for comment.

The US$44 billion acquisition is the culmination of a remarkable saga, full of twists and turns, that sowed doubt over whether Musk would complete the deal. It began on 4 April, when Musk disclosed a 9.2 percent stake in the San Francisco company, making him its largest shareholder.

The world’s richest person then agreed to join Twitter’s board, only to balk at the last minute and offer to buy the company instead for $54.20 per share, an offer that Twitter was unsure whether to interpret as another of Musk’s cannabis jokes.

Musk’s offer was real, and over the course of just one weekend later in April, the two sides reached a deal at the price he suggested. This happened without Musk carrying out any due diligence on the company’s confidential information, as is customary in an acquisition.

In the weeks that followed, Musk had second thoughts. He complained publicly that he believed Twitter’s spam accounts were significantly higher than Twitter’s estimate, published in regulatory filings, of less than 5 percent of its monetizable daily active users. His lawyers then accused Twitter of not complying with his requests for information on the subject.

The acrimony resulted in Musk giving notice to Twitter on 8 July that he was terminating their deal on the grounds that Twitter misled him on the bots and did not cooperate with him. Four days later, Twitter sued Musk in Delaware, where the company is incorporated, to force him to complete the deal.

By then, shares of social media companies and the broader stock market had plunged on concerns that the Federal Reserve’s interest rate hikes, as it seeks to fight inflation, will push the US economy into recession. Twitter accused Musk of buyer’s remorse, arguing he wanted to get out of the deal because he thought he overpaid.

Most legal analysts said Twitter had the strongest arguments and would likely prevail in court. Their view did not change even after Twitter’s former security chief Peiter Zatko stepped forward as a whistleblower in August to allege that the company failed to disclose weaknesses in its security and data privacy.

On 4 October, just as Musk was set to be deposed by Twitter’s lawyers ahead of the start of their trial later in the month, he performed another u-turn and offered to complete the deal as promised. The Delaware judge gave him an 28 October deadline to close the transaction and avoid the trial.

’Chief twit’
Since then, Musk has indulged the deal hype. He walked into Twitter’s headquarters on Wednesday with a big grin and carrying a porcelain sink, subsequently tweeting "let that sink in." He changed his description in his Twitter profile to "Chief Twit".

He also tried to calm fears among employees that major layoffs are coming and assured advertisers that his past criticism of Twitter’s content moderation rules would not harm its appeal.

"Twitter obviously cannot become a free-for-all hellscape, where anything can be said with no consequences!" Musk said in an open letter to advertisers on Thursday.

Musk has indicated he sees Twitter as a foundation for creating a "super app" that offers everything from money transfers to shopping and ride hailing.

"The long-term potential for Twitter in my view is an order of magnitude greater than its current value," Musk said on Tesla’s call with analysts on 19 October.

But Twitter is struggling to engage its most active users who are vital to the business. These "heavy tweeters" account for less than 10 percent of monthly overall users but generate 90 percent of all tweets and half of global revenue.

Musk said in May he would reverse the ban on Donald Trump, who was removed after the attack on the US Capitol, although the former US President Donald Trump has said he won’t return on the platform. He has instead launched his own social media app, Truth Social.
