Elon Musk completed his acquisition of Twitter in October 2022; Musk acted as CEO of Twitter until June 2023 when he was succeeded by Linda Yaccarino. Twitter was then rebranded to X in July 2023. Initially during Musk's tenure, Twitter introduced a series of reforms and management changes; the company reinstated a number of previously banned accounts, reduced the workforce by approximately 80%, closed one of Twitter's three data centers, and largely eliminated the content moderation team, replacing it with the crowd-sourced fact-checking system Community Notes.
