Family is usually not the best place to explore the political landscape because: 1. your family is almost certainly layman 2. it’s intertwined with other interpersonal conflict.
About your interaction. Just because someone mentions a thought does mean they are ready to take action to fix it. Their real concern may be “isn’t it disappointing that we live on a society where we can be tracked?” rather than “please give me some tips I can use to mitigate the ability to track me”.
Team dynamics are real but they are certainly not uniquely characteristic of what you’re referring to.
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.
