I'm not a windows user anymore, haven't been for a decade or so, but it wasn't until a couple months that I finished the switch when I moved from windows to bazzite in my gaming rig.

Which is why this statement is surprising. Not because I disagree with it, Linux friction is indeed unpredictable even for those of us that customized our own installation ad infinitum and know intimately the architecture of the system.

It's because friction in windows is even more unpredictable, at least with the limited interaction I had with it recently. Peripherals will disconnect randomly and removing them in order to reconnect fails. You still have to use decades old interface like regedit end device manager often to fix those issues. Random update reboots, updates that fail without useful logs, only generic error codes. And the whole culture of downloading and installing execs is the worst if all. There is the windows store, which is terrible, and chocolatey which is nice, and they aren't a full replacement for going online and downloading random binary blobs, which is a huge source of unpredictability, because suddenly every software needs to implement their own private supply chain to deliver their updates.

So all in all Linux has less friction than windows. It breaks down with updates, you go online and can usually find resources to help you fix it. Windows breaks down and it usually takes someone inside to acknowledge the problem, fix it and release in the next update, because there are some classes of problems that just aren't fixable in windows, and those that are will usually take you through a journey into the system registry that, if you asked me, didn't age too nicely.
