I think their comment is fair.

Wikipedias policies to promote neutrality are often counter productive.

Because neutrality is hard to define, what these policies actually do is progressively raise the effort required to keep or remove a particular point of view. Unfortunately, requiring more effort also means substituting the point of view of knowledgeable but time poor and inexperienced contributors, with the point of view of time rich chronic contributors and admins. The result is that instead of neutrality, you actually select for the strongest held points of view of a small ingroup of chronic users. The viewpoint diversity of such users is extremely low, which is why you’ll notice all controversial topics tend to lean a certain way.
