I'd mention Disinfopedia as an attempt to make a power structure transparent, but they as a service are so bad at making their own internal sysop power structure transparent (way worse than Wikipedia even), that they're doomed to fail. It will die as another US partisan project - Democratic Party partisan, but failing to admit that. So this is a perfect example of the real world power structure imposing one on a large public wiki which is picked up subconciously via its systematic bias.
