"U.S. Department of Justice Poised to Launch Antitrust Lawsuit Against Apple"

The U.S. Department of Justice is considering an antitrust lawsuit against Apple, alleging the company uses its hardware and software to hinder customers from switching to competitors and to suppress rival competition, such as limiting Apple Watch performance with non-iPhone devices and excluding competitors from iMessage. Apple defends its practices, emphasizing its contribution to opportunities for various stakeholders. The potential lawsuit would add Apple to the list of major tech companies facing legal challenges. Additionally, Apple is involved in a patent dispute with medical device maker Masimo over the blood-oxygen sensor technology in its smartwatches.
