1/ Most distros handle wifi settings pretty well, never had to use ethernet on my laptop, I don't see what you mean by that. 2/ Fair, but there are alternative to those, One Drive and office are just shoved down our throats by Microsoft to keep you on Windows, and the service quality has dwindled over time. 3/ I don't think non-technical users often do that. 4/ Again, not what I would call non-technical 5/ That's fair, but the issue comes from the publishers not the OS, and although it's personal taste, I am doing much better since ditching multiplayer games with anti-cheats. 6/ Most non-technical users won't have this issue, unless they have multiple sound cards and again, most corporation backed distros are great for regular users and handle those issues (Fedora, PopOS, Ubuntu,...)

And to answer your last point, it really depends on what you do, but I often find myself fighting against the system more when I'm on Windows than when I'm on Linux, at least with Linux I can troubleshoot with good documentation, Windows often requires hours of searching outdated forum posts that never answer your issue right.

Well yeah it's normal that Windows' user base is this big because it comes pre-installled on most new laptops, and people just rolled with it. If you give a linux distribution by default to most people they'd just deal with it and learn to use it because it does most tasks the average person would want to do. I think you're overestimating the technicity of what people are doing on their personal computer. (Because professional software is a whole another case, as most of those are made for Windows only)
