Unpopular opinion: Pressuring / "convincing" non-technical family members into using Linux is bad behaviour. It means that family member is now beholden to you. They almost certainly don't know anyone else who knows anything about Linux, so when they have problems - and they WILL have problems - you are the only person they can turn to. You are giving yourself power over them, essentially for the sake of your own vanity.
@hedders This is a very weird take. The real power grab attempt in this picture isn't the relatives reluctantly doing familial tech support.
Technological autonomy is a collective endeavour. That means all of us experts have a duty to try to advise our friends as best we can. Sometimes that means advising them to use some proprietary thing, but more often it means the opposite (even though often that's setting ourselves up for more work).
Please don't shame us for doing right by our friends and families.
(FTAOD autonomy also means getting to choose whose advice to follow. Obviously "pressuring" folks would be wrong, but IDK where you're hanging out, since that's not what I've ever seen or done.)
