Wikipedia is so huge that it's hard for editors to police effectively. All new articles are reviewed by one editor, but they'll likely be low-traffic enough that 90%+ of the page will be written by one person, and pages that are non-notable may survive for many years. Look at how awful some of Wikipedia's "1000 most vital articles" are (https://en.wikipedia.org/wiki/Wikipedia:Vital_articles https://en.wikipedia.org/wiki/Wikipedia:Vital_articles) and you'll get an idea for how neglected Wikipedia is. Most of these articles haven't seen significant content edits since 2010, when Wikipedia had far more editors.
