In fairness, there have been plenty of times I have had to message my mom (an attorney) for legal advice, and messaged my dad (an aerospace engineer) for help with math or any kind of non-software engineering, so it's not like they're terribly selfish; if the shoe were on the other foot they'd do the same for me.
While I do find it really irritating that they refuse to leave Windows and I do find their unwillingness to learn new stuff about computers infuriating, I do get it.
Linux has gotten a lot better and easier to use now, but historically there's a reason that it has been associated as a "nerd operating system". Prior to about ~10 years ago, desktop Linux was decidedly unpolished and difficult to use. Getting video and audio drivers working used to be a long and difficult ordeal, package managers were non-intuitive, and we hadn't fully gotten the "web apps have taken over the world" state that we're in now. I've been running Linux for like the last fifteen years and for quite awhile Linux had a well-earned reputation of being hard to use, and I think my parents are afraid of that.
It's gotten much better now, and I think a lot of people could pretty easily migrate without too much issue, but I can't completely blame people for still thinking about how crappy it used to be.
Hah, one could lie and say "Inside this window called Virtual Box is what Windows 12 will look like, it's a chance to learn it!".
