The U.S. Department of Justice, along with 15 states, has filed a major antitrust lawsuit against Apple, alleging the company has maintained an illegal monopoly in the smartphone market. Federal prosecutors argue that Apple restricts competition by imposing contractual limitations on developers and denying rivals access to key hardware and software features. Attorney General Merrick Garland stated that these practices lead to higher costs for consumers and stifle innovation across the industry. Apple has strongly rejected the allegations, stating the lawsuit is 'wrong on the facts and the law' and argues that a victory for the government would set a dangerous precedent for state involvement in technology design. Market analysts suggest the legal battle could last years, potentially forcing significant changes to the iPhone ecosystem and its integrated services.
