Isn't the CPU support reason solely specific to a new feature Windows 11 was going to use, and you can just use Windows 10 while it's still in support? Plus Windows 10 knows this and won't even try to update your PC to windows 11?
It's not a really strong argument when most hardware drivers are made with Windows in mind first, and maybe someone is going to write up a Linux driver if they're interested. I mean Linux went for years having to do some hack&slash solution to broadcom drivers until they were finally added in. That affected at least 2 laptops in my lifetime.
I will stop to say that currently, I think Linux is in a good spot. But you can't just pretend the issue absolutely doesn't exist because your specific setup works.
In the last five years, I've run Linux across a vast range of differing hardware, and I've encountered no more issues regarding driver support than I have under Windows.
I simply attach the hardware, and it works. At most I installed NVIDIA drivers via my package manager, which was simple and painless; or I downloaded the drivers as .Deb's for my Brother printer and installed them quickly and easily using the supplied script.
I'm sure I'm not the only one with such experience.
That just means you didn't use the hardware that had the issues. Which is entirely possible given the nature of hardware issues. It happens all the time on Windows as well.
