To be fair, they did a good job at decentralizing what can be decentralized, but there is still a central authority. But DNS is also mostly technically decentralized, most root servers are actually multiple machines spread all over the world, and there are several roots. People don't talk to ICANN directly, instead they use registrars that talk to ICANN. And ICANN delegates authority to TLD owners. Besides storing the database on a blockchain, ENS is not so different. Even payment is in dollars (converted to ETH, but the official numbers are dollars).
I didn't look it up too much but it looks like a key difference is that once you register a domain, it is yours for as long as you have paid for and no one can change that (or maybe it isn't, in this case, it is exactly like DNS). It is a good and a bad thing. It is good against censorship, but it also means that if someone registers a domain under your company name (or personal name) and point it to child porn, there is nothing you or anyone else can do.
