Late at night! Apple is sued by the US Department of Justice for antitrust. Apple's stock price suddenly plummeted, and on the surface of the news, Apple was in big trouble. The US Department of Justice filed a lawsuit against Apple, claiming that its iPhone ecosystem is a monopoly that sacrifices the interests of consumers, developers, and competitor phone manufacturers, driving its "astronomical valuation". This lawsuit marks the climax of a five-year investigation into Apple. The lawsuit claims that Apple used its control over the distribution of iPhone applications to hinder innovation that may make it easier for consumers to switch phones. This lawsuit may force Apple to make changes in some of its most valuable businesses.
