Hehe, you got your answer. You're lokking at the places where 0.05% of the users are discussing their problems and some others share their crazy customizations that aren't possible with anything else. And it seems like 95% of users having issues to you.
I'd argue Linux is way more stable than Windows. If that's your perspective. (Unless you do silly stuff.) But less stable than for example MacOS. It depends on which Linux Distro we're talking about. I'd say it's MacOS > Linux > Windows. With the biggest step down from Linux to Windows.
