Randians essentially believe there is only one correct opinion (i.e. that which is true according to universal Reason) and every bona fide Objectivist will (eventually) arrive at that same opinion. Otherwise, they must be misguided by ideology or something. Therefore let's make sure only Reasonable content lands on Wikipedia.
The real world doesn't work like that.
Wikipedia would be better served if it presented data in the format "According to X, Y is true" and make no a priori claims about veracity. Right now, Wikipedia is all "Y is true" with the implicit assumption that it is backed by a so-called "reliable source", which results in horribly biased and misinformational coverage of many sensitive topics.
If you want to discard everything said by CGTN or RT or NYT, fine, but let's put that decision into the user's hands (literally, with cookie-based content filtering) rather than authoritarianly deciding what is best for them.
