True, but it could not have been much better if SSH had
not been designed from the beginning to be secure,
unlike telnet.

SSH has widespread adoption, having pretty much wiped
out telnet.  If you take the attitude that software has
to be compatible with people who do not need security,
no one will have security.  It is the people who do not
need security who have to be compatible.  You probably
find yourself using SSH whether you need security or
not.
