Talking point: Musk’s new directorship comes with some strings attached. A regulatory filing states that as long as he is on the board and for 90 days afterward, he will not own more than 14.9 per cent of the company’s stock, “either alone or as a member of a group.” The appointment appears to confirm speculation that Musk would use his stake to push for changes at the social media giant, potentially including different content-moderation practices and the ability to edit tweets. Musk, who has clashed with the U.S. Securities and Exchange Commission in the past, runs the risk of attracting more attention from regulators for his late disclosure of the Twitter investment.
