If the W has a social goal to make the world a better place, it is solely through the exposition of facts.
Well, no, that's not really decided. A successful wiki is a community with an appropriate technology attached (and not the other way round). The policy comes from the community end. In time the policy approved of by most users might not be that. Of course, it might be problematic, and detrimental to what WP has done well. (Example: giving medical advice rather than presenting facts about medecine.) But it is too sweeping to assume _no_ advice or ethical component, ever.
