Better ask why not to install Linux for non-tech people. Assuming they need something installed - i.e. they're using an older computer which needs an OS refresh, their hard drive just crashed and they need help to get the thing up and running again, they bought a machine without an OS - it is much harder to defend installing Windows 11 than it is to install Mint or Debian or Fedora. It is clear those non-technical users will have a better user experience with a simple Mate or Gnome desktop than they'll have with the intrusive mess which is Windows 1X. These non-technical users will most likely want to use the web, probably mail, some chat thing and some office stuff. They'll also want to do something with media (photos, video, audio, etc). All of these are par for the course on those Linux distributions. Linux has been ready for the desktop for a long time. Windows is getting less and less ready for the desktop with every release. What it has gained in stability it has lost in being actively hostile against personal computing. Where Gates spoke about information at your fingertips Microsoft now seems to interpret this as your information at our fingertips.
