“We look forward to evaluating Beykpour’s communications and will continue to seek information and witnesses until the complete truth is revealed,” said Musk’s attorney, Alex Spiro. Twitter and Musk’s attorneys did not immediately reply to demands for comment. Musk is the world’s richest person. Beykpour, who departed Twitter after the social media giant agreed to be purchased by Musk in April, was characterised as one of the employees “most directly involved with” estimating the number of spam accounts in Musk’s court filings. As the two sides prepare for an Oct. 17 trial in Wilmington, lawyers for Twitter and Musk have filed a flurry of subpoenas to banks, investors, and attorneys involved in the deal. Twitter alleges that Musk, the world’s richest person and CEO of Tesla Inc., is leveraging worries about spam and bot accounts to back out of the deal. Musk claims the corporation has failed to establish that spam bots represent for fewer than 5% of its active users, as it has indicated in regulatory filings.
