What open source licensing could learn from Creative Commons

I have been a critic as well as an admirer of Creative Commons. Last year, here on opensource.com, I noted that the CC license suite, though inspired by open source licensing, was at odds with norms of libre culture licensing by embracing, under a single legal brand, form licenses that prohibit commercal use and creation of derivative works. The result, I complained, was “a general confusing dilution of the meaning of ‘openness’ in the context of cultural works” and confusion on the part of both authors and users of CC-licensed material. Creative Commons has recognized at least some aspects of this problem in the course of its work on the 4.0 license series. (For example, there has been an interesting recent proposal to relabel the controversial NC licenses with “Commercal Rights Reserved.”)
