he was wrong but you are way overcompensating. if windows suddenly became exorbetantly expensive, most people would just stop using computers altogether (its already easy for many people live with just a phone no PC). The remaining computer users (not counting businesses) would be enthusiasts, who are much more likely to enjoy the tinkering of Linux, or put up with it to avoid exorbetant costs. so without even gaining anymore users, Linux’s desktop market share would shoot up.

to be clear I don’t think Linux Desktop taking over is imminant or “near future.” thats nuts, it will probably always be a niche for enthusiasts and thier families/friends. but its also not going to stay eternally at 2-4%, the user experience is constantly improving and encompassing more hardware.
