Most those edits are vandalism reverts, word linking, and adding alternate languages, and other non-content edits. The article creator's original text is still largely untouched. I can only surmise that anyone who really knows the subject and is willing to fix it hasn't found it until today.

You seem to know a lot about it. So fix the article and add some specific bibliographic sources for your corrections to lessen risk of reverts.

Yes, there are a lot of horribly written, incorrect, and biased articles but it's never going to improve if no one fixes them.
