BlockBeats news, on May 9, according to TechCrunch, Microsoft's Vice Chairman and President Brad Smith stated at a U.S. Senate hearing that an internal ban has been issued, prohibiting all employees from using the DeepSeek application (including desktop and mobile versions). Although DeepSeek is an open-source model that companies can deploy to avoid data leakage, Microsoft pointed out that it still poses risks of "spreading promotional content or generating unsafe code." It is worth noting that Microsoft has not completely banned competing products (such as Perplexity) in the Windows App Store, but Google-related applications (including Gemini) have quietly disappeared.
