The Botometer tool is unreliable, Twitter said in its filing. The company noted that the tool used different standards from Twitter’s internal calculations and had once deemed Mr. Musk’s Twitter account “highly likely to be a bot.”
Mr. Musk began snapping up shares of Twitter early this year and by April had accumulated a majority stake in the company. He rejected Twitter’s offer to join its board, instead launching a swift and aggressive takeover attempt. But once Twitter agreed to the acquisition, Mr. Musk began to express doubts. In July, he indicated that he no longer wanted to buy the company.
Twitter sued Mr. Musk in Delaware Chancery Court in an attempt to force the acquisition through. Twitter has claimed he lost interest in the deal as the market slumped and shares in Twitter and the electric carmaker Tesla, which is the primary source of Mr. Musk’s wealth, declined.
“Musk refuses to honor his obligations to Twitter and its stockholders because the deal he signed no longer serves his personal interests,” Twitter said in its lawsuit.
Over the last few days, the company peppered Mr. Musk’s banks, financial partners and associates with subpoenas, demanding communications about the deal that could shed light on why Mr. Musk decided to walk away.
The deal includes a “specific performance” clause that allows Twitter to sue to force the deal through so long as the debt that the billionaire has corralled for the acquisition is in place. But Mr. Musk may pay a $1 billion fee to exit the deal if his funding falls through.
