I find it reasonable that an OS doesn't let you remove what may be the only browser on the system, for a lot of reasons.
I read this as a push to really ditch IE in the very near future, and don't really mind at all.
In no particular order
- Something has to provide a native webview for desktop applications
- MS has no default package manager for users, and doesn't provide browser downloads on their "store" (or at least I wasn't able to find any, I may be missing something). So removing the browser may leave a user unable to bootstrap another browser onto the system (at least once IE is actually gone) without outside help or another machine.
- The browser itself takes up a pretty negligible amount of disk space, there isn't really any benefit to removing it (unless MS is playing dirty and starting it behind the scenes, but at least in my usage, I haven't seen this). So these users don't want it "GONE", they just want to desktop shortcut removed (and I actually agree, MS shouldn't push as hard here).
- There are lots of system integrations that expect at least one browser to exist, removing the only shipped browser may break these, or add a lot of complexity to some feature implementations.
