Do they ask their opinion? No one asks my opinion on software/hardware and I'm the only software engineer anyone in my milieu knows at all. But even setting aside how we evaluate the anecdotes that usually warrant that claim, as far as impact goes, HN users generally sport middle class backgrounds or better; the larger population has neither met nor really considers the opinions of a software engineer and typically mobile apps, and ones which don't have their user's best interests in mind, are lowest common denominator for a target since they're interested in reaping as much information as possible. It seems easier for a layman to just install whatever apps on their phone than to consider fielding an educated opinion. HN users may just like the idea of appearing important

If you slice the demographic data finely enough, everyone is a member of a tiny minority.

My non-technical retired mom also only uses about ten apps, for basically the same reasons, although she doesn't have the vocabulary and jargon we have to succinctly explain the same concepts. AFAIK its the same for my wife, aunt, and sister (different people, LOL) who mostly use Facebook app, being middle aged women.
