The U.S. Department of Justice, joined by 15 states, has filed a significant antitrust lawsuit against Apple, alleging the company maintains an illegal monopoly in the smartphone market through its restrictive ecosystem. The complaint argues that Apple uses its control over the iPhone to suppress competition, citing limitations on third-party digital wallets, messaging apps, and cloud-streaming services as evidence of anti-competitive behavior. Attorney General Merrick Garland stated that the company’s practices have resulted in higher prices for consumers and fewer choices for developers. In response, Apple defended its business model, asserting that the lawsuit is 'wrong on the facts and the law' and threatens the company's ability to create the integrated technology users expect. The tech giant warned that a government victory would set a precedent for excessive intervention in product design. Legal experts anticipate a multi-year courtroom battle that could potentially reshape the global mobile technology industry.
