I'm going to have to agree that those who originate an idea often times have the hardest time allowing them to grow. [useful metaphor/]The reason musicians hire both an sound engineer and a producer is A: because one person can't possibly think of everything and B: after listening to a track 100 times or more you start to think its good enough the way it is. You'll fight for it just because you don't want to work on it anymore. Its even worse when the musician is the one doing the sound editing. They may not be able to let go of their original idea, even to improve it.[/metaphor] This is where Dave is tripping up on this.
Community sites and projects also run the risk of becoming stagnant when one person clings to them. The ability to let go and allow others to influence "your baby" is what allows these concepts to grow and become something new instead of being replaced by completely different concepts entirely. Sometimes, when the project takes on a life of its own, the originators sit back and complain. They suddenly go from being innovators to being no better than old men talking about the "good old days" and screaming at people to get off their lawns.
