It is. I think people are perhaps leaping to the usual discussions when models are called "open source" but here it seems they've called it free. Wasn't the whole foundational part of the open source discussion about distinguishing open and free? Edit - someone will no doubt bring up "open access" as a term. This is a common term for academic work and the license here easily meets the criteria usually applied. Open access is not the same as open source.
