I have a better metric, Linus tech tips and other PC channels are all talking about linux this year, many even for gaming, the general PC nerd is hearing and learning about linux and considering it as a real choice, so many are absolutelly fed up with windows BS and are swaping to linux. The supposed big problems of linux about having to tinker it all the time, they are just as likely to happen on windows now, except that on linux is something technichal to fix, on windows its the new update fucking everything up, and you know it will keep happening, because they are continually pushing updates, and you did not choose any or use any of those updates. My PC has been crashing about once a day for the past year for some updates that gave me nothing except more settings to turn off every time. Every PC nerd that was not already on linux has been waiting for an alternative for a long time, maybe work requires windows, maybe gaming requiered windows, maybe other people sharing the PC, but all those things are going away, there is no real reason to keep windows, its becoming a walled garden like apple, except apple has better quality i guess(never had a mac, and hated the iphone), windows is a barbed wire garden, easier to get out but if you are used to it you dont want to touch the spikes. Now a part of the fence is broken and people see that the grass is just as green or greener outside.
