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.
Just to clarify: Dutch government collapsed over the PM taking an unexpected hard stance on one of the aspects of the immigration policy, which he knew would cause the coalition to break. This is viewed as more of a political move by him than an actual case of irreconcilable differences within the coalition.
