Nothing to hide until a person has something to hide. An attitude of “I don’t have anything to hide” may catch up to a person. No one knows what the future holds. One day they might start tracking private information a person does not want tracked, for example financial or medical data. So better to put the fence up now than try to put it up during a stampede.

Personally I keep my personal data private with a reasonable amount of effort. I try to keep a small internet footprint and there’s stuff I won’t do for the sake of privacy. Going some years back the only social media I engaged in was Reddit until coming here to Lemmy. These are anonymous mediums. It blows my mind that so many people are willing to completely splay out their lives non-anonymously on social media.
