Ah! I'm sorry -- I missed a subtlety here. The CeCILL license can be
explicitly converted to the GPL v2, hence shedding its choice of venue
clause. The CeCILL-C license doesn't have an explicit conversion clause,
which is why I believe Francesco feels it is a problem.
Okay, this is actually a somewhat reasonable concern, in my opinion. The
FSF does declare other licenses as being GPL-incompatible for having
choice of venue clauses. See, for example:
I agree that this may actually be a problem. I don't think it's a
particularly *large* problem -- historically, we've not treated choice of
venue clauses with a great deal of urgency. This is also relying on the
assumption that a library linked with a GPL v2 library requires every
other library linked with it to be relicensble under the GPL v2, something
that I think we believe in principle, but which we have not always
enforced elsewhere in the archive.
But I was wrong to dismiss this -- the choice of venue clause is usually
something the FSF considers problematic.
