What principle? Are you saying you weren't disputing the principle that there are two different kinds of things that people call "censorship", in practice and in theory? It is a difference in kind, not degree. You can have an arbitrary number of rules, enforced by human and machine, for acceptable behavior in a forum. I think that's basically the case on HN or reddit. But if you have an optimizer that filters and reorders things on top of that, then any particular item that is moved or removed is not against any rule. And nobody can really say why, even if they are informed of what happened. The latter thing is what many people, including me, think is terrible, and the distinction is not fuzzy even if you can call it all "censorship" or "curation".
