Beyond that, a desktop OS without a browser installed is largely a dead duck. Most people install browsers using a browser. The first thing I do on a new Mac or PC is launch the default browser to download Chrome or Firefox.
Browser technology is a core OS function at this point and being able to launch a browser has become an essential capability users just expect to be there. Platform components, support processes and some applications might rely on it being there. Imagine a user installing Firefox then deleting Edge, then forgetting about it and deleting Firefox, or Firefox becoming unusable due to an extension or malware. Suddenly the user is functionally locked out of the internet. I think Microsoft has a legitimate interest in making sure users can't easily get themselves into that sort of situation.
If I can uninstall then I do not especially care if it is pre-installed.
I'd say that is a big piece of software already.
Windows users can't uninstall Edge, therefore it's fine if Android users can't uninstall Chrome.
