ChromeOS runs Debian in an LXD container. You can install desktop apps in it (e.g. using Flatpak) and they appear as launchable icons on the ChromeOS desktop. Being LXD you're not just limited to one container either. I have additional multiple containers with Ubuntu and AlmaLinux on my Chromebook and can use other LXD features to snapshot and publish them as required. This is far from being "useless".

Windows also runs Ubuntu. That's really not a good reason to use it

You can? I thought it ran on a totally nonstandard stack meaning no X, PulseAudio, systemd etc. How do regular Linux apps work? Is there some sort of compatibility layer?
