But on the application server side, Linux is extremely popular. Config management via some tool like ansible or puppet is a table stakes skill in that space. Likewise with some kind of ldap based config for users. I would actually be surprised if someone said they did "devops" and they meant they managed anything with Windows. Typically that's "IT", but I don't understand why.

KDE is also an obviously more "professional"/"serious" desktop environment that just makes it easy to open the tools to do work without a bunch of crap to turn off and without pointless UI churn requiring people to relearn how to use it. As far as bugs go, Windows IME has to be rebooted around 80% of the time after sleeping because either the WSL driver crashes or the VPN enters a permanently locked up state. I've had the start menu just stop responding to clicks when everything else is working normally. The thing is wonky as hell, and usually needs to be rebooted via the "hold power for 10s" method (do normal people even know about that?). I never run into issues on Linux (Fedora or Nixos).

The UI is also trash. e.g. if you type "reboot" or "restart" in the start menu (a common need, per above), it doesn't find the command you obviously want to run (KDE does for both), and it hides the (unlabeled pictograph) button you'd need to click to find it, requiring you to close the menu and re-open it. Nothing is organized anymore, so you need to rely on search, but search doesn't even work.
