This is certainly true, and the statement that NPM is _run by_ "morons" is, while immature in its phrasing, at least potentially aiming toward a legitimate point.

However, the post in question also labels NPM's _users_ in broad strokes as "morons", which can make no such claim of legitimacy. It's just a puerile, baseless insult that is devoid of content and detrimental to the poster's credibility.
