Wikipedia isn't a "global source of truth" anyway, so i'm not sure what they're worried about. They've got serious biases and underrepresentation, and they're kind of under the control of a cabal of elite Wikipedian feudal lords who shove out the majority of outsider attempts to introduce content that doesn't fit their worldview.
