it's not that all those who complain are seeking a direct fix, or don't even care if the devs see their post. sometimes it's about bringing together multiple relating instances to "said complaint", via OP, and hopefully with more conversation and discussion that chimes in are all constructive and full of reason. sometimes said complaint was just a misunderstanding or mistake and again, others chime in to give feedback. so as a whole, if you find other players with similar problems it brings us together and issues become resolved or they make the post that much stronger and maybe a dev will hear it.
just because we dislike something doesn't mean we don't push for change. some people do give up and sell the game, they just don't like it... it happens... and there are those who as i said push for change. as "humans" finding flaws is in our nature, and if something can be done about it what's the harm in crying out?
there are things on the game i could complain about, but it's more personal preference than mechanic issues. if there's a good enough post with a legitimate complaint... +1 and ill make a comment.
