Core devs are actually a small group of active ones, there are yes many more but most are not active. This small group of devs is so centralized that they control Bitcoin top to bottom. They claim all they do is for decentralization yet they refuse to recognize that there are just as many users on the big block side as there are on the small block side. They also attack and try to demonize anyone who does not fall in line. They claim others are trying to centralize control yet they already have. Here is just another example of them trying to control through fear.
