Musk, critics trade shots over Twitter

Driving the news:

• Critics of Musk's purchase issued a letter calling on advertisers to insist that the service maintain its current content moderation policies, including bans on users who spread hate and harassment.
• Musk, meanwhile, questioned the motives of critics and also hinted in a separate tweet that the company may charge some businesses and government entities to use the service.
• Oh, yeah, and if he buys Twitter, Musk might take it public again within a few years, per the Wall Street Journal.
• Separately, Twitter announced it is testing Circle, a new feature that lets people share a post with up to 150 friends rather than posting it publicly.

The bottom line: Twitter, its users and employees are in for a wild ride. The company acknowledged as much in a regulatory filing, warning Musk's purchase could lead to revenue loss and employee attrition.
