But in fact Bitcoin is run by a small group of people IMO, that decide things like how the blockchain works. Of course they will claim it's a democracy but in fact it is not, nor should it be. The people who put the hard work in coding get to call the shots as to how bitcoin will work. Most of them post here so unofficially this is the official site.
Yes, but if they want their holding to be more valuable they are forced to allow others in. What good is a developer's coin if nobody uses it? I think most of the people involved have worked on software projects in small groups and dealing with large numbers of people/ideas is out of the normal things they do. You can tell when they try to shoehorn everything into Github and IRC chat.
