Because for many non-technical users, using a computer or anything computer-related automatically disables thinking. Using a computer boils often down to waving a magic chicken, performing a ritual, and then the computer does what it was istructed to. (Or not, and this is where people call support.) I actually saw this several times on myself with regard to something I knew I know nothing about, i.e. power tools. I avoided them like a plague, because I knew I don't know how to use any of them at all. I needed to be taught a little how to use power tools (mainly: how they cause accidents and harm).
