Lies and mistakes persist on Wikipedia for many years. They just need to sound truthy so they don't jump out to Wikipedia power users who aren't familiar with the subject. I've been keeping tabs on one for about five years, and its several years older than that, which I won't correct because I am IP range banned and I don't feel like making an account and dealing with any basement dwelling power editor NEETs who read Wikipedia rules and processes for fun. I know I'm not the only one to, because this glaring error isn't in a particularly obscure niche, its in the article for a certain notorious defense initiative which has been in the news lately, so this error has plenty of eyes on it.

In fact, the error might even be a good thing; it reminds attentive readers that Wikipedia is an unreliable source and you always have to check if citations actually say the thing which is being said in the sentence they're attached to.
