Browser Choice Alliance v. Microsoft

On November 26, 2024, a group of major browser developers, including Opera, Vivaldi, Google Chrome, Wavebox, and Waterfox, formed the Browser Choice Alliance to challenge Microsoft's alleged use of dark patterns to limit users' ability to choose alternative browsers on Windows systems. The coalition accuses Microsoft of deceptive practices like making it difficult to download rival browsers, resetting default browsers during updates, and coercing users into using Microsoft Edge through prompts and service integration. The Alliance has called for regulatory action, urging the European Commission to classify Edge as a “gatekeeper” under the Digital Markets Act (DMA), highlighting concerns about unfair competition and consumer rights.
