I love Linux and I think a lot of my non-technical family members would benefit from it, but I am not as brave as you. The danger with messing around with someone's computer is that you are basically taking ownership of all tech problems the person may run into. It's like the "You break it, you buy it" rule. The person may seek help from another tech geek, but as soon as that geek finds out they're dealing with a "weird" Linux system, they're going to run away from it. You are effectively volunteering to be 24x7 on-call tech support for the people whose laptops you've installed Linux on.
That's a gatekeeper-y take. I tried Linux a few years back, so I guess I became a "real" tech geek a few years ago. Never mind the fact that I was 3/4 the way through a CS degree, I'd built my own computer, and was the go-to tech guy in my family. But nope, not yet a tech geek.
Yeah, I'm not sure what OP is on about or how they get away with it. I'd get phone calls for how to use outlook and MS word. I'm fortunate to have a fairly tech literate grandma, but she is old, which means set in her ways. She probably could use Linux, but she would not see the point in putting in the effort to switch habits.
