should also seriously consider whether the non-commercial clause is really necessary.
Rutledge (2008) notes that some believe that any for-profit businesses should not be able to charge course fees or make use of open content, hence the NC restriction. However, this would imply that a private school may not use NC materials (Hofman & West, 2008), nor potentially a for-profit organisation using materials for non-profit work such as a corporate social investment project. Other arguments against using the NC restriction include that it makes the materials incompatible with materials licensed without this restriction (see for example Bissell & Boyle, 2007; Moller, 2005).
While it is understandable that an author who openly releases their materials would not want others to make a profit from them, this can be achieved in other ways. For example, it could be argued that, when materials can be freely accessible via the internet, charging for the materials themselves becomes irrelevant, and to make a profit the individual or company would need to add sufficient additional value beyond what is available for free to make it worthwhile for users to pay. Work released under an attribution-share alike licence requires that any work that is derived from the original work is released under the same licence. Thus, the value added by the for-profit individual/company would itself need to be released freely under an attribution-share alike licence (Moller, 2005).
