A class action has been filed in the Western District of Washington accusing Microsoft of misrepresenting Copilot and Azure performance; Microsoft fell about 10% on Jan 28, 2026, with a lead-plaintiff deadline of Aug 11, 2026. Microsoft is steering sales to pitch its AI models, emphasizing faster, cheaper, easier-to-use alternatives with end-to-end integration across Azure, Microsoft 365, Office apps and Copilot. Microsoft says Unilever cut costs by ~ $300M after shifting to a cheaper Microsoft AI model for automated claims processing, citing Microsoft CEO Satya Nadella.
