Yes, I am arguing it is centralised. Read about the centralised root signature system that is the way to add new TLDs to the system.

Also this is worse than the current system we have in the world because it wastes more energy in doing so!

It claims it is a decentralised naming system, though looking deeper you will find it is just clever marketing and underneath is it is only ethereum-platform based naming for anything like your address etc. will only work in eth browsers, not all etc. which I have already mentioned in my OP.
