I used to be an editor, and an admin. Quite a prolific one, in fact. I eventually quit (not really "officially", I just gradually ran down my frequency of editing until I eventually realized I just wasn't any more) because editing Wikipedia was no longer fun. And as far as I could tell, that was deliberate and as-designed.
Rules, rules, rules. No articles on quirky topics for the sake of quirky topics. Strict limits on pop culture. Articles for Deletion became a death sentence, arguing felt like trying to be a lawyer in a court that had already ruled against you and was just making things official. Just a tiring slog to produce something I wasn't terribly interested in any more.
Not really sure what the solution is, if there even is one. Wikipedia seems to be what it wants to be, now. I am a bit saddened because what it used to be was fun, but I've moved on. I'm glad Wikipedia still exists and has been useful to a great many people over the years.
