Because Linux is Niche. It doesn't as far as I know come pre installed at the store when you buy a computer. Etc. That's why people still use Windows.

I personally don't find anything wrong with Windows. I use it for work and home and it's fine.

How do you know if somebody has Linux on their desktop?… They'll tell you. I'm currently on Windows 10 Pro but have used a number of different Linux distros since the mid-90s. I also had to have Windows because of work requirements but now that I'm retired, I may go back to Debian or Kali.

Windows user here, have used Linux here and there too:

Gaming. It's gaming. Yes, Linux has workarounds and options, and some people are super knowledgeable and willing to go through those hoops. I'm not, not anymore.

I spent a little bit of time hunting down and eliminating W11's annoying behaviors, and now I don't mind it at all, and I get to just jump in games with very little hassle.

I'm pretty excited about the future of Linux gaming now that steam OS exists and Linux is a super viable target for developers, though

I only use Windows because I have no other choice for work, otherwise I only run linux. I fully believe the average user could easily switch to linux but it's just not worth their time normally.

Right because windows also continues to make things easier to use and does the bare minimum to maintain modern aesthetics and most people like it or not just don’t care about bloatware or telemetry. Simple as that

I might make the switch, but what I really want is for Microsoft to get their shit together.
