I have this same experience. I put ubuntu LTS on a family member's computer back in 2011, made sure the browser icons were big and front/center, and the support nags stopped. They said they loved whatever I did. I think there is some security-by-obscurity in there too, where all the insane spam/fraud/virus stuff couldn't even work on ubuntu if she ended up clicking on one. Nowadays I take it with a grain of salt: The support nags might have also stopped because other family got scared I would wipe their computer and put this new thing on there they were scared of having to learn.
