Not quite. But maybe so.
We don't (at least I sure *hope* we don't) permit users to determine which
packets will/won't be permitted into our networks. We set those policies
to maximize security, because we recognize that malicious/dubious network
traffic is a threat. So for example, we might have in place a mechanism
which begins to reject ssh connection attempts after a certain number of
failures. There is no real difference between that and rejecting SMTP
traffic -- recognizing that spam is *also* a security threat -- other than
the application protocol involved.
Users are not qualified to make decisions about (for example) SSH traffic
management in perimeter firewalls. Nor are they qualified to make decisions
about about SMTP traffic management in mail servers. That is why they
are users and not network/server managers. (They probably get to make
some other decisions that network/server managers don't. It works both
ways: each according to their expertise and responsibilities.)
This is NOT the same thing as determining for a user (to go back to your
remarks) what "[they] don't want to receive". That's a personal preference
and users are of course free to formulate/express it as they wish.
I don't think this is elitist, I think it's a matter of recognizing that
the spam/not-spam classification process requires expertise *vastly* in
excess of that possessed by almost all users. This is not their "fault"
per se because it's not a fault: it's simply a lack of area-specific
experience and knowledge.
