Counterpoint of what exactly? Blocking ports by default is okay, and will address the clueless user problem (clueless users won't change the defaults to begin with). It's blocking them no matter what that's evil. Now I live in a country where most ISPs lend you a "box", a router, which is capable of doing all the blocking they want, and is configurable by the user. One of them uses that box to block the SMTP port by default, and let the users who want to change that setting. Problem solved.
