He's such a terrible historian, so I can't really see his sociology or political theory as worthwhile.
Regarding originality, I think he suffers the same problem as early Eliezer - failure to acknowledge sources. It's not that big a problem for Eliezer because most of his sources (logical positivist philosophers, Dennett, etc.) would agree with, or at least respect, the new conclusions that are being drawn in the sequences.
Moldbug's citation problem is much bigger because many of his interesting ideas are straight from thinkers who would disagree with his conclusions. Further, Moldbug's core audience is very hostile to those thinkers.
Konkvistador cites previous discussion of Moldbug's view that religion deserves to be treated like an ideology. I don't disagree, but Marx's "Religion is the Opium of the People" can plausibly be read as asserting a very similar point. And the Chomskist Po-Mos take this idea even further, asserting that just about everything is an ideology. Likewise, "everything is an ideology" is the basic justification / explanation for Paul Graham's "Keep Your Identity Small." or the local Politics is the MindKiller norm.

Of these examples I see nothing that I would characterize myself as being hostile too. Except some of the more silly aspects of pomo.

Summary: Moldbug on the Aaron Schwartz affair. Power is a very real thing with real consequences for activists, yet many people don't understand the nature of power in modern times. People like Noam Chomsky get great fame doing bad epistomology about who has power, and as a result do great harm to idealistic nerds who don't read between the lines to selectively target their attacks at weak institutions (Exxon, Pentagon) instead of strong ones (State, academica incl. MIT).
Here he returns to a theme that is one of his real contributions to blogospheric political thought: that victory in political competitions provides Bayesian information about who has power and who doesn't. If your worldview has the underdog somehow systematically beating the overdog, your epistemology is simply wrong - in the same way, and to the same extent, as a geocentrist who has to keep adding epicycles to account for anomalous observations.
This means that activists like King, Schwartz, and Assange are only effective in bullying the weak, not standing up to the strong (despite conventional narratives that misassign strengths to institutions). When such activists stop following the script, and naively use the same tactics to attack strong institutions, reality reasserts itself quite forcefully:
