Some weird narcissism you're selling to convince people they shouldn't care about privacy. Immediately refuted by everyone's real world experience with visible privacy violations.
I'm not selling anything. I don't think my point was refuted. I think it was verified by how many people (including myself) just gave a random website camera access and let it scan our faces.
Your point isn't verified because it can be explained by other reasons (curiosity about its effectiveness seems likely, especially given the nature of this community).
The effect you describe is certainly real, but you only have to look at the present reality to see just how far it extends. In modern society, people are mostly not comfortable sharing their intimate thoughts with random service workers. And that's with individual humans, with faceless machine networks the tolerance might be lower.
