I don't think you understand how decentralization works - it depends on the actions of individuals taking responsibility for the system/network. You seem to want someone else to do everything for you or for perfection to arise magically. The accounts were removed at the inception of the network since the network was created as a direct response to the actions of the operators of the accounts who were removed. There is no perfect system, there is only mitigation of risk and response to challenges that arise.

The forking of decentralized systems is their ultimate defense against corruption, which is what occurred. You are welcome to create something better.
