Its actually cfb who has a vendetta against me, it began when I asked in iota slack "PoW on IoT? srsly?", "why no auto-node discovery"? and "why does a coordinator exist if its so secure", back in 2016 december, then he banned me from slack and came here to harass me. 

First of all, Coordinator doesn't lead to centralization, it just protects against 34% attacks. Second, switching it off would mean that IOTA team made a centralized decision. Instead of that every users will be given a choice when to abandon babysitting from Coordinator, this is a truly decentralized approach.
