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.
I do need to explicitly call out one point here. Making edits to an existing page is often ignored. Creating a new page is always reviewed by somebody; and there is a consistent backlog due to a lack of volunteers to do the reviewing. As a result, many promising stub articles are treated quickly and poorly. There's no solution here other than to find more reviewers (which does take quite a bit of project-specific knowledge; you need to understand reference formatting, categories, article structure, etc.).
