Yeah, I've heard people say, "I don't use it for anything controversial, but it's accurate for other stuff." That's usually true, but you can't assume it, because you never know what will be someone's personal hobbyhorse.

If I just want to know some dry facts about Podunk, BFE, it'll probably have them right. But maybe not, if the mayor of Podunk wrote the page and is trying to promote the town, or if it was last edited by someone who used to live there and hates the place. And very few people are going to check the talk or history pages to see whether there's been an edit war or other hints that the page might be sketchy.
