there are commerical products that use OSS stuff that they didn't mention

Ah, but I think you'll find that many of the products or services in the article make use of OSS in one form or another. SpamAssassin is easily the most widely used anti-spam technology available, and it will likely play a part in most vendors' anti-spam technology, ours included. We also make use of Postfix, Apache, Linux.. the list is endless.

My point is that businesses without the tech savvy to configure their own anti-spam systems (and that's most of them) will want to pay someone else to handle it for them. If they're smart, that someone else will use the best tools that exist, which is almost always OSS.

The reviewer simply chose to include several commercially available products or services which meet the needs of businesses looking to handle their spam problem. That they didn't make mention of OSS in the process was a mistake IMHO, but then how would they compare the Free options' cost to implement? (And don't try to tell me that it's zero, because FOSS takes time and expertise to master, both of which are not nearly as tangible as a price tag on a box). My 2c, anyway. Take it or leave it; I'm biased either way.
