At some cross-over point of course mircosoft becomes the larger threat actor.
I still have a single windows laptop for VR. Steam VR games don't quite seem to work ok for me on proton yet, sadly. (Most other games do, fortunately). Since that particular laptop only makes very limited network connections, an update is plausibly a net negative for me already.
I'm sort of surprised there's no straight-forward "block windows updates" firewall for the raspberry pi or so, or is that what pi-hole is for?
