A couple comments (that I may not be remembering properly) seemed to
imply that these credits are part of a revenue generating model. Folks
who wish to require users to see their name in conjunction with ReiserFS
may purchase this control over what ReiserFS users see (i.e., they can
purchase an ad -- the first TV ads worked exactly like this, that's why
the word "sponsor" is used to refer to ad purchasers). If this is the
case, and you are using the license to implement this control (i.e.,
option three above), then I think it's clear that you intend your
license to work exactly as it appears to, and restrict users' freedom.
If this is your goal (or perhaps some other variant on item 3 above)
I don't think you're going to have much luck convincing folks on d-l
that your license is Free.
