After six months of public and legal battle over the agreement, Elon Musk finally completed his $44 billion acquisition of Twitter Inc., according to people familiar with the situation, placing the world's richest man in charge of the faltering social network.

One of Musk's first actions was to replace the leadership. According to persons with knowledge of the situation, departures include Twitter CEO Parag Agrawal, director of legal, policy, and trust Vijaya Gadde, chief financial officer Ned Segal, who joined Twitter in 2017, and general counsel Sean Edgett, who has served as Twitter's general counsel since 2012. According to two of the people who requested anonymity because the details are private, Edgett was led out of the building.

On October 4, Musk decided to move forward with the terms he had first suggested, and a Delaware Chancery Court judge granted the two parties until October 28 to complete the transaction. That deadline was met, and now Musk, who also serves as CEO of SpaceX and Tesla Inc., also has power of Twitter, which he frequently uses but openly criticises and which he has promised to fundamentally alter. Shares of the company are not anticipated to trade on the New York Stock Exchange anymore.

Many people have expressed dissatisfaction with Musk's involvement, and some have questioned his suitability to lead a social networking company.

Many Twitter employees have expressed worry over his support of a far-right political candidate in Texas and sexual harassment claims made in May by a former SpaceX flight attendant. Some staff members made fun of Musk during a video Q&A with Musk in June on internal Slack channels. Through the course of the agreement, other people publicly mocked or chastised him on Twitter.
