No... This is a matter of expectations. When I use and RBL, I expect
the hosts in the list to be the source of spam, not the source of spam
software. They are not breaking what a reasonable assumption of the rules
by distributing software.
Now, don't get me wrong I don't have a problem with these aggressive RBLs
existing. In fact, I think that they have a Constitutional basis for
their existence because people have the right to associate with whomever
they want as long as the rules and consequences are known upfront. RBLs
serve a valuable purpose, but IMO it is a good idea to depend on them as
the only factor in keeping or discarding possible spam.

I poked around and it looks like the suits against MAPs have been either
settled or dismissed. I was pleasantly surprised by this.
I think that "restraint of trade" is more complicated than you are making
out and is not restricted to monopolies, but you would have to ask a
lawyer... It looks like people have tried to sue RBLs, but I didn't find
anything other than temporary orders that were later lifted. Again, I
think that MAPs and other RBLs have the right to do what they are doing
as long as the end customer knows what they are getting from the service.

Yeah, but if I had a problem with UPS because they shipped something to
me I didn't want I wouldn't be allowed to stand outside other people's
houses and keep them from delivering the package to my neighbors. In
effect that is what is happening in some cases where a naive user signs
up for this blocking service and can no longer do business with a
company that happens to be on an ISP that happens to sell software that
some RBL decides is spamware. It isn't as clear cut as you are trying
to make it.

So far :-). I suspect more and more people are going to move to permission
based messaging for their personal email where you have to give someone
credentials that they need to present before you accept any correspondence.
This is already happening with instant messagers and this will be eventually

Works for us... For me it works so well that I though the mail server
was down :-). It has made things pretty tolerable and for the most
part made my wife happy. I may cut my home network off from at least
Asia because I'm still getting some spam and hacking attacks from
overseas. Though it would be nice to keep Australia and Japan in the
list, but it looks like they mixed in pretty good. Currently I am
dropping all packets except for SMTP and HTTP for these networks:
