Why does Microsoft even care about having a browser? I can see the need for a rendering engine within Windows for various tasks, but do we really need a Microsoft browser, especially yet another Chromium browser?
If they do feel like a browser needs to be bundled, why not just add a minimalist, privacy focused browser. The goal should be to have tech savvy people tell friends and family to "Just use Edge and you'll be fine".
It is just to drive people to Bing? If that's the case, just promote Bing, it's a good search engine.
