It is decentralized in the sense that it is not centralized, i.e. there is no central entity in control managing entry into the network.

The key point is that any node in a p2p network can be used to join the network, so any number of independent entities can publish lists of ways to join the network.

Certainly, i would also love some multicast/anycast support on the IP level, but we don't have that, so making sure that you have many independent entry points into the network is the next best thing.

Maybe you're thinking distributed, not decentralized? https://i.imgur.com/YsiiKeq.png
