Wikipedia is an authoritative source of information, has been repeatedly tested and examined for accuracy, and is cited by experts often.
Yes, it's banned in universities, but that's largely as a holdover from when anyone could edit it. Wikipedia is repeatedly tested to be more accurate than Britannica, which has never been banned.
It doesn't matter anyway, as Encyclopedia articles are summaries, and the actual sources can be referenced.
In this case, the article is correct, explains why it is correct, and certainly trumps your baseless assertion.
Its use as a source is specifically banned in every academic institution I've attended over my entire adult life.
