It is my understanding a lot of people maintain their unhealthy relationship with Windows as a prerequisite for keeping their unhealthy relationship with Adobe.
To be fair, the FOSS community in this area has categorically failed. GIMP's mission statement is 1. be hateful to use and 2. be capable of editing photographs I guess. Inkscape can't support CMYK colorspaces so just forget it if there's an outside chance if it's going to be printed, Krita can't draw a circle, Pinta crashes every other thing...hell I wonder if Adobe pays the GIMP team to keep it unusable.
