They are better with their physical privacy (i.e. gated mansions and tall fences), but the ones who aren’t tech-literate (i.e. non tech bros) are likely the same as everyone else, and are probably even worse off than privacy-conscious regular people. I remember Zuck uses Signal, so we know at least the tech bros who are technically literate (and not the ones who only pretend to know what they’re talking about) are aware of their personal privacy.
This and surveillance pricing are good arguments against the nothing-to-hide-nothing-to-fear crowd, the next time you get into a debate with one.
