David Wiley opines on whether Creative Commons Non-Commercial materials may be used in university classes with what I believe are two non-sequitors. The first is that a 2009 survey of 'users and producers' suggesting they believe use by a tutition-based university would count as 'commercial use'. The second is the argument that "There’s only one person whose interpretation of NC matters, and it’s not yours. And it’s not mine. And it’s not Creative Commons. It’s the LICENSOR whose opinion counts." But of course nothing follows from what these survey-takers or content-producers believe. People can have incorrect beliefs about the licenses they use; that certainly has been the case with people using CC-by licenses.
