It's just kind of funny that the vast majority of game servers, near monopoly on web servers, majority of business machines, a near monopoly of supercomputers, the majority of mobile phones, tablets, netbooks, every other console(basically not XB1), Smart TVs, and a smaller share of desktop/laptops in consumerspace are not using windows as the primary OS.
I saw some statistic about games on linux being only 0.5% market-share for steam. Then you look at how the numbers are tracked, well... herpy durp, if it's a gametree/cadera/wine/crossover package being run on linux ormacos, then it's going to register usage as whatever windows version. And the thing is, with how wine works, the software/games have native execution on linux or mac, which is why wine is not an emulator or the games are not a port. They just use wine to launch the executable, and all wine does, is keep the windows file structure and library list in tact to make the game cross platform.
So yeah, I do not trust these numbers whatsoever.
