I think _your_ impression of people outside tech circles is as HN-centric as it gets :)
My no-tech middle-aged uncles and aunts know what apks are, and that you need to install apps from somewhere apart from the main Play store if you want them to have no ads.
And how do you qualify "(e.g. HN)" for this purpose? Places where people value openness?
These feels like a no-true-scotsman.
