Most avoid computers. My parents use'em and click everything they come across with. Decade ago I installed Linux in their shitty old computer, just so I can remove everything they can use to screw up the OS.
Everything was fine for few years till my father bought a new shitty low end computer from the black friday with all kinds of support and additional warranty BS that needed Windows with VNC that they really didn't understand.
So, the result of that study is BS. One reason is that people selling old people expensive shit they don't need is not considered a scam.
