With or without Elon Musk, Twitter is overdue a shake-up

acquisition of Twitter was to be one of the biggest buy-outs in corporate history. Now it threatens to become one of the ugliest disputes. On July 12th Twitter sued Mr Musk in a Delaware court for pulling out of the $44bn deal, as the world’s richest man—and holder of Twitter’s sixth-most-followed account—took to the internet to engage in battle by meme.The argument may play out over months. But whoever prevails in court, Twitter has bigger problems to reckon with. Though it is one of the world’s most talked-about social networks, it has struggled to turn that clout into a successful business. Whoever ends up owning the app will press its managers for change.
