I'm glad you posted that information, because it really shows that random online information can often be wrong or conflict with other online authorities. Here are two quotes from an article that was posted 10 years after your link. [1]
"There has been lots of research on the accuracy of Wikipedia, and the results
are mixed—some studies show it is just as good as the experts, others show
[that] Wikipedia is not accurate at all."
and later in that article They found that in general, Wikipedia articles were more biased—with 73
percent of them containing code words, compared to just 34 percent in
Britannica.
