This article isn't in the main namespace, it's in the Wikipedia namespace, which is dedicated for essays and meta discussions about Wikipedia. The rules for deletion of Wikipedia-namespace articles are very different than the rules for deletion of main-namespace articles. Even if it were deleted, the author could migrate it into his/her personal user-namespace User:username/<article title>, and it would have an even lower standard for inclusion.
