This discussion made me reflect on the term openness in terms of degree.
Simply, everyone should have the freedom to use any type of license that is available – I typically refrain from judging which creative license is “better” than another. Each type of license provides different degrees of openness and I don’t see this changing anytime in the future (if ever); that is, an open educational resource under a Creative Commons License typically falls along an open and closed continuum. There are many types of teaching and learning contexts that exist and it is unfair to generalize the importance of any particular type of license over any other. When I see groups develop a licensing policy (that usually singles out one or a few acceptable licenses), I am quickly reminded of how my own learning is networked based (i.e., connective) as opposed to group based (i.e., collective).
