Sage is neither. The Sage
It is difficult if not impossible to come up with a general legal principle of this type covering all software. The basic idea, I think, is that when you use software to produce a tangible creative work then you own the copyright of the part you created. License that part as you wish. In the case of Sage, the sws file produced by the notebook is yours. Of course, we hope you will license it under the cc-by-sa or GFDL or something like that and allow us to post it on the wiki or in some web directory where others can access it, eg http://sage.math.washington.edu/home/wdj/teaching/worksheets/ > notebook can be used as a code/latex/html editor, but that is not how > most people use it.
