> exactly 0% of people I have spoken to where it's come up in conversation care at all about privacy or surveillance in general with the old "nothing to hide" fallacy.

But they do have something to hide.

Are they going to the toilet more often this week? Are they booking a flight for a funeral? Do they watch midget porn? Are they interested in science experiments that go boom? Did they just get a promotion at work? Did their car just fail the yearly inspection? Are they going on vacation and leaving the house empty for a week? Does their child have ADHD? Did their catalytic converter just get stolen? Is their phone model no longer receiving security updates? Is their child bullied at school? Did they have an abortion? Are they contemplating bankruptcy? Did they just start using a CPAP machine? Did they vote for an independent candidate? Do they listen to the local mosque's podcast? Do they smoke? Are they closet homosexual? Are they being sued? Did their dog just suffer liver failure? Did they put their teenage daughter's child up for adoption?

These are all things that your phone knows about you, which could lead to negative consequences if exposed - ranging from embarrasment to blackmail, higher prices to actual denial of services, scrutiny to arrest. Everyone has something to hide.
