I don't mind talking to my parents or grandparents, but I just want our conversations to be about something else than computers. There is nothing worse than being with your family, and constantly dreading the moment they are going to ask about 'fixing their computer'. It makes one look forward to talk with one's (grand)parents.

When you regularly get calls to fix this or that and spend 30-min to half a day or more dealing with whatever problem they have, there comes a time where enough is enough and you get them a Mac or install Linux.

Also, it's not just parents or grand parents. It's also siblings, in-laws, and their respective close circles.

So this comes down to "After I switched my parents to Linux, they don't want to talk to me any more"...

It can be. Not in my brother’s case, though - he lived with my parents and my mother used to harass him about computer problems daily. Linux helped, but now she has a Chromebook and her computer problems come down to confusion about where and how she is signed in.
