Personally, I’ve always thought “They could sell your data to insurance companies who might jack up your prices or claim something is a pre-existing condition” to be the most p we persuasive to people like my parents.

But Facebook/Twitter/etc isn’t telling out boss what we say about them at home. Or our SSN to every car we pass. Or how much we hate it family-in-law.

Unless you give them realistic reasons, they will always counter with “That’s different” because it is.

I keep seeing people saying “I have nothing to hide” is a bad argument. But no one ever explains why it is. So for the people who say they don’t care about the privacy, what would you say to them about why they should care?
