I think most people here are missing the point. You need not convince them that they do have something to hide, or that other people have good reasons for hiding things. The key point is that you do not get to decide if you have something to hide. When you share data extensively with companies or the government, they now have the power to use it to make decisions about you. They may use that power in ways you disagree with. They may punish you for things you don’t think are wrong, or deny you employment for reasons you think are stupid, and so on. It’s not your decision that you are perfect and have nothing to hide; they get to use your data and decide that. Daniel Solove has expressed a version of this argument before, that privacy is really about power, and it is compelling: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=998565 https://papers.ssrn.com/sol3/papers.cfm?abstract_id=998565 Moxie Marlinspike makes a similar point that positive social changes, like acceptance of homosexuality or marijuana, require the ability to do socially disapproved things in private. With no privacy, the changes would never happen, because nobody would have been able to, say, privately have a same-sex relationship. https://moxie.org/blog/we-should-all-have-something-to-hide/ https://moxie.org/blog/we-should-all-have-something-to-hide/
