Who uses telnet anyway? It's deprecated. Everyone uses ssh for any kind of

TELNET != login.  Before you utter those words again in the same
sentence, please read the Telnet RFC.  Notice how the term "login"
appears nowhere in that document.

Telnet is a general purpose way to obtain a remote terminal connection.
That it is sometimes used for remote logins is simply a byproduct
of terminals being used to remotely log in to hosts.  But it's far
from the only thing Telnet is used for.
