I was using “decentralized” to mean that there isn’t centralized control over ownership of the service in general — eg anyone can spin up their own server (impractical, imo, pushing it more towards being centralized) and people can use it (making it decentralized, imo (Please correct me if I am wrong, but I do think my usage of the term is appropriate in this way.)), but people who use that server can only communicate with that server (making it not federated). But yes it could still be said to be centralized in that it operates on a client-server model [1].
This is more an argument of definitions, though. I’m not trying to claim anything in bad faith.
No it’s not. From literally your own comment:
