Then here are two things you could do:
 - expand your FAQ / documentation; or
 - simplify your licenses.

Indeed the question I was asking has been asked several times by my users.

Fortunately I think I've been able to figure it out, see:


I'm interested in any comment you might have on this interpretation.

We are free software developers. This is for the Eigen project,

We are a free software project, not even accepting donations, so our
financial resources are zero.

I don't see a problem with the FSF offering paid consulting services
on its licenses, as long of course as it doesn't constitute a conflict
of interest against simplifying these licenses and/or documenting them

Already done.

(already addressed that misunderstanding).
