Why would you want to use a closed source OS controlled by a corporation with a past as checkered as Microsoft's?
I wish I was exaggerating but I've had these arguments with people that really should know better and there was nothing I could do to convince them. There's a lot of people that are strangely proud in being completely technically illiterate and they don't care to actually have control over their computer or personal data. This isn't an age thing either; this was from people that were otherwise my age or younger that simply got angry at the mere thought of Linux.
I myself made the full switch last year with the advent of them forcing copilot shit everywhere and everything just works out of the box. I originally thought I might need to switch back to Windows every now and then for gaming but no, everything I've thrown at it works great and often better than it did on Windows. I only keep Windows around on my separate dev/work machine for the sake of game dev and coding.
