The unpublish document describes the options that users of NPM have to remove packages themselves. It was created after some situation where someone unpublished an important package.
A whole different set of terms governs which packages NPM can remove. This definitely includes these packages, either as "abusive" or "name squatting"
Not only that, but NPM's TOS makes it very clear that you have no recourse if they decide to remove your package for any reason.
