I frequently hear complains from people about individual Wikipedia pages but most of the people who complain only complain outside of Wikipedia. Wikipedia is inherently democratic. If you read a Wikipedia article and think it's very problematic, take five minutes and write about why it's problematic on the talk page of the article.
Wikipedia is an important part of the commons. If you think from an EA perspective those five minutes (or even more if it takes you time to search for sources) have a good chance of being time spent with a good EA return.
While recruiting people outside of Wikipedia to individual pages to engage in discussion goes against Wikipedia's rules, simply engaging on Wikipedia and voicing your opinion is helpful. It makes it more likely that consensus on the article shifts in the right direction.
Wikipedia sadly is not as democratic as you might think: https://www.nakedcapitalism.com/2021/01/wikipedia-the-overlooked-monopoly.html
Some more anecdotal evidence: My life partner did her PhD on a historic consumer organization in my country and the additions, edits and corrigenda she proposed to the wikipedia article were rejected.
So Wikipedia is like the worst of both worlds if you compare it to historic encyclopedias (who were vast works with contents curated by professors/experts and professional editors): Like the old world, it still is not as democratic as we would want it to be, and it lacks the academic rigor we can expect from something like the Encyclopedia Britannica. It's just that the editing/moderation power has moved to faceless people on the internet.
For the record I don't think this comment deserved negative karma
