Elon gone? Elon Musk lost a poll on whether he should remain head of Twitter ( TWTR ) Monday. "Should I step down as the head of Twitter?" Musk asked hundreds of millions of Twitter users, noting, "I will abide by the results of this poll." "As the saying goes, be careful what you wish, as you might get it," Musk tweeted after posting the poll. As the poll closed, more than 17.5M had responded, with 57.5% saying "Yes." It is unclear whether Musk has succession planning in mind for Twitter if users vote him out. In October, Musk, the world's richest man until recently, completed his $44B acquisition of Twitter, leading to the immediate resignations of its then Chief Executive Parag Agrawal and Chief Financial Officer Ned Segal. Musk also said in a follow-up tweet that "there will be a vote for major policy changes" at the company in the future. "My apologies. Won't happen again," he added amid uproar over Twitter's decision to suspend some journalists from the social media platform.
