Mr Musk sacked about half of Twitter’s 7,500 staff when he took over in 2022 in an effort to cut costs. Meanwhile, Twitter is struggling under a heavy debt load. Cash flow remains negative, Mr Musk said at the weekend, although the billionaire did not put a time frame on the 50% drop in ad revenue. Twitter has lost almost half of its advertising revenue since it was bought by Elon Musk for $44bn (£33.6bn) last October, its owner has revealed. Rival app Threads now has 150 million users, according to some estimates. Its in-built connection to Instagram automatically gives the Meta-designed platform access to a potential two billion users. Is Twitter falling as Threads takes over ?
