I don't buy your explanation. I said extended family, there isn't really interpersonal conflict. If anything a personal relationship should convey a bit of "this person works with technology and perhaps knows what they're talking about".
I also didn't present it as "you should do this" or worse "it's your fault", as we often see in many ham-fisted HN comments. Rather it was more like hey it is actually possible to defend against this thing we both feel is attacking us. As I said, the problem was they were not interested in the idea that it's possible to avoid surveillance.
