You are manufacturing an absurd allegation. Wikipedia put the wikiness of their model right in the name. If an "average user" doesn't bother to research their resources [0] or understand modern language then the problem lies somewhere in our educational system, not in the number of disclaimers on internet websites. It takes a special kind of curious person to want to find information on a subject but not wonder where it came from.
