Yup.

The internet firewall you sit behind at work allows telnet out, but blocks
ssh, so you listen SSH on port 23.

Or rather did until (a) you change jobs and no longer have the requirement and
(b) you get sick of all the telnet probes.


I think the main reason public telnet was still there was mainly for access to
library catalogues. These generally predated "web", and some still exist. Most
have shifted to web tho, I believe.
