> Microblogging in the fediverse somehow does not trend towards social pathologies.

The fediverse, too, trends towards social pathologies; something or some things is causing craziness on all the mentioned platforms, even if the exact manifestations vary. For example, well into 2023, almost daily among the top-ranking posts on Mastodon was one advocating for harsh anti-Covid measures: e.g. that live music and theatre should never have been permitted again, insisting on masking in public at all times, etc. This was after countries lauded for their responsible Covid response had already returned to normality. The fact that posts like these could get such a welcome reception, sending them to the top, says something about how highly online and out of touch a significant portion of fediverse users are.
