Why should someone pay for rules software when you can just get JESS for free?

Well JESS is a technically-oriented language based squarely in the dark days of artificial intelligence exploration. It is a lot of fun for tech-heads to fool with, but it doesn’t really have the level of support, the interfaces, or the usability to base large scale enterprise business applications on. If you want to get business users to maintain the rules, one of the key benefits of business rules technology, you'll need something else.

In answer to the comment posted, I don't think availability is a valid driver for industry analyst coverage - they cover what their customers ask about.

While I know that JESS is not really enterprise class, do you think an industry analyst firm should be able to provide an objective comparison in terms of a research report within this space?
