Self-styled "Chief Twit" Musk has fired much of the workforce, fudged the rollout of the new Twitter Blue subscription service, and alienated advertisers, users, and remaining employees alike with his relentless pursuit of free speech.
The latter point has involved reinstating banned users – including Donald Trump – and ditching content moderation policies. Needless to say, advertising revenue, which is Twitter's big earner, has tanked.
The EU is threatening to ban the service, while US regulators are mulling a review of the takeover. There's even speculation that Twitter could go bankrupt.
