Then after all those 'problems' I should be seeing tons of users choosing a Linux Desktop distro (which one out of millions) mass migrating out of Windows by now. Why is that still not the case yet after 20 years?
It seems that after 20 years, these users still do not care enough to do any of that and WSL2 has only given a reason to make backing up / migrating / wiping / installing a Linux Desktop distro even less worth it these days.
Why do you think they aren't? There's a massive gaming on Linux movement which is only going up, and Chromebooks are outselling Apple Macs. Most main OEMs sell Linux-compatible devices, that come with Linux preinstalled.
So when we say 'Linux' we're now talking about 'Chromebooks' with ChromeOS.
Not only they defeated the purpose of someone else's point on getting rid of 'closed source' and 'spyware' controlled by Google, it is already at risk of ending up getting replaced by Fuchsia but may still be called 'ChromeOS' and it won't be based on Linux. That is my bet on this decade.
I still don't see any evidence of Windows being challenged by any Linux Desktop distro other than being used in WSL2. That is it.
There are marvelous cleaning products for that, you should inform yourself.
2% market share on the desktop market, or people giving big bucks to Apple instead of supporting Linux laptop OEMs, don't need rebutals, they are well known facts.
As for Android and ChromeOS, keep padding yourself on the back, maybe one day you can run Gimp on them without layers of VM and containers.
I think Windows being a product of a big company also played a role. It mainly came pre-installed on most device. Because Microsoft pushes for it, and user, especially the non-technical one, won't bother to install something else on their machine. So, for most computer user, there is just no other choice.
You're making the presumption that more popular is better. You're also heavily implying that linux desktop users should care that it's less popular - I genuinely don't. 2022 is another year of the linux desktop for me, and I'm so glad to be off windows again.
