The problem isn't just the petty tyrant fiefdoms, it's also the exclusive claims on generic terms like "news". So, instead of generic news, you find hyperpartisan content on "r/news". Once someone cybersquats on a generic term, other perspectives are forced into qualified subreddits that more accurately describe their bias, "r/conservative".

I think it would greatly improve the site if communities using generic terms were instead replaced with disambiguation pages that linked to related communities, and that this process could be triggered automatically so that as terms become generic the communities could be remounted.
