I just re-read that policy article.  It says that an article mustn't be based entirely on primary sources (this one isn't), and it also doesn't say that there must be a certain minimum ratio of primary-to-secondary sources.  It doesn't even say that secondary sources must be in the majority.  So, officially, I think the article is on firm ground.  But I don't think that's going to stop Verbal from cutting stuff out.

I just noticed that the policy article also says, "Articles may include analytic or evaluative claims only if these have been published by a reliable secondary source."  But to the best of my knowledge, I've never done that.  All throughout I have honestly tried to convey the material in a factual way.
