I suspect at some level of deliberation in MS, it’s as simple as wanting a predictable and controllable view portal to their content and site resources, rather than worrying about Google or whomever else “accidentally” and temporarily breaking something. I know there’s a lot of room to push on this - that MS themselves have myriad broken links and useless endpoints on the web so a browser is least of their worries. Nonetheless, the thinking may be about predictable user interface between the OS and the manufacturer’s online resources.
