The US Justice Department and 16 attorneys general have filed a historic lawsuit against Apple, accusing the company of anti-competitive practices that secured the iPhone's dominance. Apple warns that the case could drastically transform tech companies' ability to serve customers, setting a dangerous precedent if the DOJ wins. The lawsuit focuses on five key areas where Apple is accused of hindering competition. Apple insists that its approach is aimed at providing high standards of privacy and security for its customers. However, a loss in this legal battle could discourage tech innovation and have negative implications for consumers.
