Elon Musk said Saturday his planned $44 billion takeover of Twitter should move forward if the company can confirm some details about how it measures whether user accounts are ‘spam bots’ or real people. The billionaire and Tesla CEO has been trying to back out of his April agreement to buy the social media company, leading Twitter to sue him last month to complete the acquisition. Musk countersued, accusing Twitter of misleading his team about the true size of its user base and other problems he said amounted to fraud and breach of contract.
