I see. My confusion was from 17a) "Licensor ...declares that it is a
not-for-profit organization" which I interpreted as the basic requirement
with the additional requirement "derives no revenue... from the

This was not clear to me but now I see it from the "otherwise" sentence in
17d) "Otherwise, You shall distribute... under the OSL..."

This was unknown concept to me in open source licensing. Now I see, also
from Rosen's document , that the point of NPOSL are the different
warranties for non-profit organizations.

Certainly the confusion would be one reason. How I got to this was that I
wanted to write somewhere that if the license is on OSI list, the software
can be used commercially. Just to check myself, I went to the page with the
list and I see "Non-Profit... License" which I haven't noticed before.
