1. This post seems to take for granted that schisms are bad without actually arguing why. Even if it is the case that schisms beget more schisms, that in itself (or that + pointing at Protestantism) is not actually an explanation of why that’s actually bad; it just claims so. It does imply that the badness is in the coordination costs that are increased by a diaspora over a centralised location, but if a diaspora happened in the first place that is strong evidence that whatever central place it spawned from was not only incapable of making this level of coordination happen but also its members judged it was incapable of hanging into a place that can do coordination.
I’m not sure that it’s the case that people correctly judged that it was incapable of changing. Reforming an existing space is often harder than just taking your ball and going home, but the benefits are shared across the entire group.
2. Two of your main examples are religion and politics, where one can’t really belong to multiple subgroups. For things like the LW diaspora or Discord servers or w/e, schisms aren’t schismatic – one can belong to multiple social groups and Discord servers and what-have-you (which can even be desirable, as you yourself have argued in your post about diversifying your friendship portfolio).
Belonging to multiple social groups and Discord servers and the like is nice, but belonging to a bunch of different groups that are all sort of doing fundamentally the same thing (and claim that others are trying to do the same thing but doing it worse) isn’t as good. When people found servers that are like “this is the same as <SERVER X> but with better moderation>” that tends to split the community (and indeed things like this have happened multiple times with Discord, online forums, etc.).
