Does there have to be a a threat model for people to be uncomfortable with or unsupportive of surveillance? I just bought a new android phone, and if you accept the defaults they track so many different things (not even while you are using a google service necessarily). I disabled it all, and am constantly prompted to enable location history and a bunch of other tracking features. I don't like Google, I don't like their business model, I don't like how they go about what they do; a threat model isn't required to fundamentally disagree with an inescapable organization collecting and analyzing everything about me so it can be, at best monetized, and at worst used to manipulate people
I don't have a "threat model", per se -- I haven't written anything down or drawn anything. However, I do use the term "threat model" in conversation. What I generally mean by this is "I've given a lot of thought to what/where the biggest threats are in my life and the steps I'm willing to take accordingly". My threat model is an informal mental-model more than an actual document (like the threat models I create at work).
