Sorry to be blunt, but you sound like an terrible person with an over-dimensioned ego.
If you do not want to support your family, fine - no need to announce it to the world. You are free to do that of course, but you have to bear the consequences of people saying "what a [put your favourite expletive here]" instead of "what a wise person to battle against mighty [put your least-favourite tech here]".
I support my parents with their tech even if it is often full of things I would not have used. I roll my eyes up and fix it. And ask them not to do this anymore, and they still sometimes do.
This is not that different from them telling me, 40 years back, to not do this and that. And me still doing it. Boy, I am really, really glad they did not decide to stop supporting me until I grow up :)
Honestly, read what you wrote again and take a step back to say "ok, this sounds really bad".
PS. when you gain back a lot of time for not supporting these technical noobs, make sure to fix your site that has plenty of problems - it does not look good for an "Itinerant Engineer" who built the impressive number of 11 web sites.
