perspective, it's more of being proactive to help protect the network, the
end-user and help keep SLA's (keep from getting listed on RBL because of a
non-patched or virused pc, not wasting network resources due to SPAM, trying
to keep your own house clean, etc) more than it is an attack on Net
Neutrality.

But on the other hand, the end-user, customer, or whoever is having a port
blocked, might wonder about the services they are buying and if it's time to
jump ship to another provider if they aren't willing to work with the
customer.

I think that most providers are willing to work with the customer if ports
such as SMTP need to be unblocked for whatever reason. If they aren't, then
i would suggest finding another provider.
