There are a few “unresolved matters” about Twitter Inc, and he wanted to put the takeover “on hold” while he investigated how many of Twitter’s users are real people, said Elon Musk about his takeover of the social media giant. “There is the question of, will the debt portion of the round come together and then will the shareholders vote in favour,” Musk told Bloomberg News Editor-in-Chief John Micklethwait at the Qatar Economic Forum in Doha.According to The Star Malaysia, Musk said that ‘twitter filed a formal letter with the US Securities and Exchange Commission in which he told Twitter executives he might walk away from the deal if the company didn’t do more to prove the size of its user base.’Twitter responded by giving Musk access to its full fire hose of public tweets, though it’s unclear if that data is truly helpful in calculating the number of bots on Twitter.
