> I've got nothing to hide.

I'm sure you believe that's true, but I suggest that your belief is based on a certain confidence that the people pouring through your data are fundamentally acting in good, or at worse neutral faith.

However, if this data ever gets into the hands of someone acting in bad faith, even the most innocent behaviour can be weaponized against you. Let's say, for example, that you are wrongly suspected of committing a crime, and the investigating police are more interested in cooking up a conviction than determining if you actually did it.

All sorts of details about your life can be leaked and "spun" to make you look very, very bad. You went to a bar on a certain evening? So did these known crime figures. Were you meeting them?

You spend time on Hacker News. HACKER NEWS. You could find yourself the target of a smear campaign designed to turn public sentiment against you.

"If you give me six lines written by the hand of the most honest of men, I will find something in them which will hang him."—Cardinal Richelieu

If you hand over your data without hesitation to a nation-state or to powerful and unscrupulous corporations, I believe you will discover that there is no such thing as "nothing to hide."
