Mr Trump and Mr Musk are both brilliant users of Twitter. But they are also hard to predict. Donald Trump was fiercely critical of Twitter when he was banned, supposedly for life. After the Capitol Hill riots Twitter said the permanent suspension was “due to the risk of further incitement of violence” and for Mr Trump it was his way of connecting directly with voters, bypassing the traditional media. Ironically, it was also a way of getting attention from the media he claimed to shun. “He’s tweeted” was a regular refrain across the world’s newsrooms. Will Trump return on Twitter ?
