Vivaldi spoofs Edge to access Bing Chat as AI wars turn vicious

To fight what it considers to be unfair gatekeeping of its browser, Vivaldi said that it's masquerading as Microsoft Edge to enable users to gain access to Bing Chat. The new Vivaldi 6.1 update tells websites that it's actually Microsoft Edge, using what it calls Client Hints. Vivaldi has used this technology before, identifying itself as Google Chrome, to try and accomplish the same task. Now, the company says, some websites are seeing through its mask and blocking Vivaldi regardless. If you access Bing's AI-powered Chat feature on Edge, the browser allows you to converse with Microsoft's AI chatbot.
