The United States Supreme Court is considering taking on a court case where Apple is being sued by a group of consumers. They are pursuing a class-action lawsuit alleging that the price of apps in Apple's App Store are high because it is anti-competitive and monopolistic. Since all software that is allowed to run on an Apple iPhone has to be purchased through the App Store, the market for apps on the platform is closed to competition. Apple argues that it acts as only a conduit; the prices set are up to the app creators. Apple charges developers a 30% commission on the sale of apps in its App Store. Apple has blocked Valve from bringing its Steam Link app to iPhone users because it allows for in-app purchases and other reasons. The justices, and the court system more broadly, have regularly wrestled in recent years over how old laws should interact with new technology, sometimes raising the question of whether current law is adequate to address a rapidly evolving technological landscape. In this case, it was clear the justices had at least some familiarity with the issue through their own iPhones. A decision is expected by the end of June.
