[I deleted a part of this comment where I incorrectly attempted to correct the OP] I have no good ideas about how to solve this problem, I’m guessing that the smaller audience a wiki has, the more likely it is that an ideological faction will have influence on the content. The first thing that came to mind for me was making all of the other non-English wikis read-only machine translations of the English version since it has the most eyeballs on it. The problem with that is, then you miss out on things that are notable (by Wikipedia standards) in other languages that don’t have sources in English, which isn’t fair to non-English speaking countries that have their own notable culture and history. Enforcing an NPOV across all of the wikis across many different languages (or even just the English wiki) seems like an intractable problem. And that’s without opening the ‘what is a neutral point of view’ can of worms.
