I don't consider Wikipedia a valid reference for anything more trivial than sports statistics or Hollywood trivia these days.
I'd imagine the amount of blatant organized 'revisioning' by nation states, NGOs, for-profit corporations, and politically biased individuals is now dwarfing the objective individual contributors who once were the majority of Wikipedia's editors.
