In this case, I think it is the news agency that is doing the redacting, not the government. The article says, "one other country, which The Intercept is not naming in response to specific, credible concerns that doing so could lead to increased violence".
Well, it's still pretty effective when they black out 3/4 of a document, which we sometimes see. And even in this case, though we might know the country, we can't quote the source on it.
That kind of thing makes it astonishing that government agencies still consider blacking-out a sensible mechanism.
