I pretty much agree with you. In most cases, there is no reason to run
SNTP as a server, and doing so is a waste of resources.
Telling clients the time is the job of an NTP-based server, not an
SNTP-based server. Usually.

And there are more cockroaches on the planet than people, but that does not
make them a higher life form.

The operative word there is "seems".

Yes, and there is nothing to indicate that if it is an SNTP-based server
that it *is* connected to a proper refclock, either, or that the time from
the refclock is "sane".
We basically need more information, including knowing exactly what is
expected as far as accurate timekeeping is concerned.
