I do agree with the Linux argument you are making, but you cannot swerve 50% of the global Windows users into Linux. It still doesn't have the best UI reputation (although it gets the job done).
Also, I don't want to hear the UI argument when KDE Plasma exists. I bet 90% or better of Windows users would be comfortable on Plasma.
this is exactly 100% dead on the money
prior to Windows 10 Microsoft was at worst known for producing unreliable mediocre quality software, but they were trustworthy (at least for the end user)
Windows 10 changed everything, at the point you're fighting the company that made the OS to not spy on you, not show you ads, not reboot against your will and not reinstall random crapware you previously removed: it's time to switch
Lack of suitable software can be a dealbreaker for some professions. There aren't many professional video editing suites, for example. But in companies I've worked at, most workers only need a browser and an office suite to do their jobs. Linux would work for them.
I think the real obstacle is training. You have a workforce that's already used to the way windows works. It's easier to hire IT people with windows experience than it is with Linux. Users know how to do their tasks in Microsoft office, and even though Libre office is similar, they might have to learn a few new things.
