You'd be surprised how many people in the software engineering tutoring/mentoring group at my university -- the students who are more interested than anyone else in writing, sharing, and reading code -- who know no more about FOSS at all than that "open source" means you can download it for free, or do whatever you want with it. I'm not simplifying; many have not learned of the concept of software licenses in the way many FOSS contributors have.
It seems to me that the website is taking the position of explaining free software from first principles, rather than as this branch or strain of open source that you already have to understand to really get. I think that's a good thing.
