Certainly you need to control server how you see fit and make sure is all running stable and the like. But, not letting your community have a say in parts of the server isn't a good thing if there's something the community doesn't like they will leave you. Plus, what about the users that do know what they are saying? They know whats going on and you couldn't just ignore their opinion at least i can't. As well as plenty of people who threaten leaving do not return.
