ely, i don't know where you bring these odd claims from, but:
1. ssh does not sit on top of telnet. it sits on top of tcp.
2. ftp also does not sit on top of telnet. it sits on top of tcp.
3. the same goes for http...
you'd better sort out your confusion by reading a good book about the TCP
protocol family (internetworking with TCP/IP, by douglas commer, for
example).

it is the telnet protocol itself that is insecure. some telnet
clients and servers did override this problem by moving the authentication
part into using a more descent method (e.g. kerberos). alas, you cannot
interoperate them with telnet clients/servers that use the normal
(RFC-based) telnet protocol.

what they were explaining is that when you control a complete network
(e.g. your HOME LAN, or when you're an administrator of a site), then you
can disable telnet/ftp and let all your users use ssh instead.
