You can say that about Encyclopedia Brittanica or any of the old-school encyclopedias too. You can say that about the news desks at ABC, CBS, CNN, etc. You can say that about the New York Times, Washington Post, Guardian, etc.
I don't think people tend to blindly trust Wikipedia any more than they do for other sources of information. YouTube is full of garbage Wikipedia-regurgitating articles because Wikipedia is an easy, centralized source to scrape, not because of any level of trust they put in it.
I find this type of snap negative reaction boring, tiring, and unhelpful. It's disappointing that they often end up as top comments here. (Human psychology at work.)
My take: I expect that Wikipedia is more unbiased and a better reflection of reality then most -- maybe even all -- other sources of information on the Internet. On average! There are certainly crap articles, just like anywhere else.
