Noam didn't say blocking port 25 for everyone is a good thing or that he likes it - just that this is what ISPs in Europe and the US are doing that to fight spam. What Noam said is that ISPs have a responsibility to prevent spam being sent from their hosts. He also said that blacklists may not be the smartest thing in the world, but they are deployed and in use - once that's done it's the ISPs responsibility for its users to not be listed. It is unfortunate ISPs choose blocking port 25 as the easy way to do that, but like I said it's the current common practice. By the way - just to set the Linux-IL record straight - Imri has been extremely helpful to us in several "abuse" cases we contacted him with. It wasn't necessary for him to do that (that's what the abuse desk is for) but he did it anyway, and I applaud him for that. But that doesn't mean we don't have our different PoVs...
