We disagree. But is this really the place to discuss what MARKETING
people should be doing? :)
Blocking port 25 is not, IMHO, a violation of Network Neutrality. I
explained why in a very long, probably boring, post. Your definition
of Network neutrality may differ. Which is fine, but doesn't make
mine wrong.
As for how it is marketed, well, I'm not even going to try to argue
that.
