Yeah but if I were to meet someone new in person, I’d tell them my name. If I meet someone new on the internet where I have a handle, I wouldn’t want the company of the site I am using to actually know my real name. That doesn’t make my name a secret, more something private to me and those I choose to share it with. If a website then correlates my handle to my other behavior on the internet and finds say my name via Amazon shipping info or whatever, then that’s a violation of my privacy, not secrecy.
Maybe a name isn’t the best example, idk, but there’s an apparent distinction between something secret or private imo.
