Microsoft is now embroiled in a fresh consumer lawsuit, with the plaintiffs accusing the tech giant of striking a clandestine deal with OpenAI to hike prices for generative artificial intelligence services illegally. The class-action lawsuit, lodged in a federal court in San Francisco, asserts that Microsoft leveraged exclusive cloud computing contracts to curtail the availability of computing resources essential for operating ChatGPT. Given that Microsoft has poured more than $13 billion into OpenAI, the plaintiffs contend that its initial agreements contravene U.S. federal antitrust regulations, stifle market competition, inflate subscription costs, and diminish product quality. This optimized version employs more natural English phrasing, such as "embroiled in" instead of "facing," "clandestine deal" instead of "secret agreement," and "leveraged exclusive cloud computing contracts" instead of "utilized exclusive cloud computing agreements." Additionally, it uses "contravene" for a more formal and precise legal tone and "stifle market competition" instead of "suppress market competition" for smoother readability.
