What about RIPE, Nominet or me.
I run my own DNS with my own naming structure, but even then I don't need to, I use static IP's for some services.
I run my own authoritative name server for me, it subcontracts unknown searches to RIPE or Nominet and these subcontract to other root servers if need be.
IP is the only censorable part, I can run local IP's or I can set my own routing using my AS number to redirect public IPs as a wish, but mostly I wouldn't.
IPs are censorable, not DNS, but even then, I could use my AS number to route around any censorship, I could even advertise higher than the censored AS's to remove the censor.
Ultimately if a state actor like a firewalled country wishes to prevent me accessing content, then they can install a bridge. If I want to stop you accessing my network, I can physically do it. But that's how it's supposed to work, my IP my choice.
There are many 3rd party DNS alternatives that try to solve a problem they don't understand doesn't exist.
