Just to clarify the hate for Wikia though....what you said is correct.
"I know a few wikis there that are actually decent. Arguably even better than those run independently."
The thing is...that's not why we hate Wikia. While some of us do dislike some certain specific Wikia wiki's (those which have engaged in plagiarism, or deceptive practises), overall we don't dislike the individual wikis. What we do dislike is Wikia as a organisation, and how it operates in its relations with the fan communities it hosts, and the wider fan communities they are a part of.
I mean, hell, theoretically, a wiki farm could start up with people running it who actually care about fandoms and work together with wiki communities to make something that the wiki communities are happy with, without imposing on the wiki communities in any way. If that started up, we wouldn't have a problem with it whatsoever. Hell, we'd be all for it. I know of some (non-Nintendo) wikis out there in the wilderness which have corporate owners (who otherwise have no involvement in the fandom, so not a situation like the Guild Wars Wiki has), but where these owners don't interfere in the day-to-day running of the wiki, and where they work side by side with the wiki community to make something that everyone's happy with. That kind of situation is damn rare, but it can and has happened.
