Only if the preceding sunset you shot every ISP that doesn't offer
static IP addresses as an option for their services at the same price
as the dynamic dns servers (i.e. - between $0 and $5/month). When the
choice is between $5/month for dynamic DNS services, or a couple of
hundred a month for collocation services, guess which I'm going to
pick?

I did make sure I'm not in violation of my TOS. I also think I
convinced them to fix their monthly open relay tests to bounce to
them, not me.

Mine certainly wouldn't. Running FreeBSD on a dialup account, I used a
relay, just like Windows. Of course, I used (horror of horrors) an
open relay run by one of the five ISPs I used when I was using a
dialup account. Because that was the only sane way to avoid having to
reconfigure my mail system every time I connected to the internet.

ISPs that don't provide services that some users want have to expect
that others will pick up the slack. If they feel like those users are
"working behind their back" - well, tough.

From what Ted said, he's one of the ISPs that tries to accomodate
green(*) users. That he suffers because other ISPs are less
professional and create a market for dynamic DNS services is a shame,
but no more so than that green users suffer because of spam-prevention
measures. Those things are part of life on the internet these days.
