The US Department of Justice and 16 state and district attorneys general accused Apple of operating an illegal monopoly in the smartphone market in a new antitrust lawsuit. The DOJ and states are accusing Apple of driving up prices for consumers and developers at the expense of making users more reliant on its iPhones.
No, these are not illegal activities until you add “as a monopoly”. Antitrust laws are fine with all sorts of behavior as part of competition but not when you dominate a market and it keeps new competitors out
Everything here will hinge on whether Apple is a monopoly in the markets of concern. I’m sure there are legal definitions and precedents for that.
