One other way of saying “drives away people who give a fuck” could be saying those people are self-aggrandizing, self important, always yelling at the top of their lungs about their zealotry telling everyone at first opportunity about how they turn off JavaScript and don’t contribute the much to the discussion

I liken people like this to the Amish. They balk at modernity as being incompatible with their beliefs. So they withdraw from the world and live life as they see fit.

What they don’t do is go around all the time yelling at people telling them how their lifestyle is wrong or constantly telling other people how they don’t use certain technologies.
