You talk about decentralization and anonymization, but you take the sole decision about the hardfork. It does not work like this.
You're missing the point. It's an open source project, anybody can add code. It's up to the network(miners) to accept it or not.
Even now, the miners could have just continue to use the old code and different fork, but they chose to update. This is quite decentralized no matter how you twist it.
