The trend that bothers me the most is excessive use of the em dash accompanied by awkward use of semicolons.

> Cooperators who are scattered among cheaters get eaten alive — the lone honest man in a crooked ward is not noble, mathematically speaking; he’s lunch.

There's also the not-quite-right logical link between clauses (I see this a lot in Opus output):

> Parasites are a constant; every era grows them to maximum greed, because that’s what parasites do.

("era grows them" doesn't fit with "that's what parasites do." If the era grows them, the parasites aren't doing their own growth.)
