I have always been curious about this. Did you get them to use other services or did they stubbornly refuse and you just accepted it? I am talking using Chrome, using Windows, using social media like Tiktok or Facebook or Instagram, etc. Bonus points if you have kids because that is even more work in the privacy realm
I think protection from data breaches is the most real world, relatable case you make for digital privacy. There are tons of victims you can point to that have suffered in a way that is easily understood by even a normie. It’s a much better tactic than trying to compare it to people looking though a window or some other vague/unrelated idea.
