Apple’s ecosystem play has — at once — been the envy and bane of the consumer electronics industry for decades. Following a lawsuit filed by the U.S. Department of Justice on Thursday, it’s now also at the center of strong antitrust charges levied against the hardware giant.

The sweeping lawsuit, jointly filed with the attorneys general of 16 states and the District of Columbia, focuses primarily on the iPhone and controversial practices like the company’s walled-off approach to app sales. The Apple Watch gets some face time in the filing, as well.
