This is a primary reason why not many people use RBL's anymore except for the handy dialups.mail-abuse.org. It's much more accurate to use the likes of SpamAssasin at receipt time than simply reject receipts based on RBL's.
I have to disagree there -- somewhat. Had a single false positive here (a Korean manufacturer got caught up in my wholesale block of .kr) but otherwise, I'm a happy DNSBL camper. It's undoubtedly different for ISPs who probably can't say goodbye to all email from .ng for example. IDG's running SpamAssassin in tag-mode currently, and that seems to produce a lot of false positives. It's mostly due to PR agencies having a penchant for WRITING THINGS IN ALL CAPS etc. I'm sure you can tweak that out, but even so, SpamAssassin means you have to receive the message first, before filtering. Seems less wasteful to just drop'em early on in the connection. Correct me if I'm wrong here.
Although that's probably not what the journalist meant. He probably actually meant "the web" because in luddite consciousness the internet is simply whatever is in that fancy looking "IE" window of theirs.
