It's not really at scale. Everyone is still at least partially aligned. There's no critical mass of militant single cause people to come in and hijack it. Otoh, it's as big as it is because it's a benevolent dictatorship, not any kind of democracy. It's heavily moderated with enough (I mean this positively here) citizen policing, in the form of moderation and flagging, that it stays pretty much on mission.
