> There's a strange morality here: at what point is it unethical to voluntarily disclose data about oneself, if it could be used in a way to harm someone else's privacy?
At what point is it unethical to exhale, given that carbon dioxide is toxic to humans and is a greenhouse gas? At what point is it unethical to vote, given that you might influence an election in a way that is bad for society or some subset of society?
It's true that nearly every (and the "nearly" is just a hedge) action we take has some negative externality. I personally don't lose sleep over the ones that are virtually impossible to measure.
