Maybe a silly question, but: why hasn't this affected Linux? I assume it uses a proprietary kernel module just like it does on Windows. I guess this will come out in a post-mortem if they publish one, but it's been on my mind.

They did do this to Linux, but in the past. Maybe whatever they did to deal with it saved Linux this time around
