I have randomly sampled many articles in the Featured Articles page which are some of the best articles Wiki has to offer wow some are good NB I dont see PETA listed I found that many articles have criticism sections Many have controversy sections Many have Trivia sections The articles provide all the info the reader requires in a welllaid out format Look at this one Canadian Charter of Rights and Freedoms for example I could care less about what the article says as with PETA to be sure  but I care deeply that it says it all and it says it right The crtisicsmcontroversy sections do not seem to be attracting undue attention in those articles I suggest the reason for their excellence is that these articles are written correctly being unbiased balanced and written by authors who have no agenda In short the reasons you list do not withstand scrutiny even though you make think they do  that is the definition of specious
