I am not sure I understand what you are disagreeing about.

What I say is:

 (A) the CeCILL-C license includes some restrictions (at the very
least, a choice of venue clause) which are not present in the GNU GPL
v2 (or later)

 (B) the CeCILL-C license does not include any explicit
conversion-to-GPL (or to any other license) clause

 (C) a license which includes restrictions not present in the GNU GPL
is GPL-incompatible, unless it has an explicit
conversion-to-GPL-compatible-license clause

Which point are you disagreeing on?
Please clarify.

Thanks for your time.
