His point is that you don't need a working domain name since the MCP can just hardcode the IPs of the servers or resolve them through any other method that isn't DNS.
Would be fairly easy for them to offer an onion service on which they publish the current list of domains, as one option among many, many options for distributing small strings on the internet in an uncensorable way.
Ideally it is common knowledge that the onion service exists, and then people can go look at the onion service and update Wikipedia based on what they see there.
If you are really interested we could try piping their [API](https://encyclopediaapi.com/products/index) to some printable format. Maybe we can even find a quality print on demand service or bind it by hand :)
