Does this comment about the first article you linked respond to your concern?
Regarding the second article, I just don't find it that interesting. Yes, it is worthwhile to notice how the ideas of the Protestant Reformation impacted later social justice movements up to the present day (i.e. morphological analysis). But there are lots of Reformation ideas, and not all of them transferred over to modern liberal thought (either the classical liberalism of Locke or the Fabian socialist liberalism of the community organizer).
And there's lots of ideas in modern social justice movements that doesn't descend from the Protestant side of the Reformation. Some Reformation ideas oppose later social justice ideas. That's my biggest problem with Moldbug - he constantly describes conflicts as two-sided when a more useful analysis would describe them as multi-sided. And, as shown by his whole Cold War = State Dept. v. Pentagon theory, Moldbug isn't particularly accurate at correctly labeling even if we grant a conflict only has two sides (I don't grant that about the Cold War, but that's probably a discussion for another day).
To pick another example, Moldbug's discussion about taking the political middle ground. His first observation - what currently is middle ground was quite radical for most of history - is true. And obvious to any serious student of history. The conclusions that Moldbug draws from that accurate and insightful point just don't follow at all.

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:
