necessary for that software to comply with laws or regulations which are
not inconsistent with this Agreement.

relate to patent applications or granted patents, including any orders
made by a judicial authority in relation to patent disputes, subject to
safeguards against unauthorised disclosure under the law or practice of a
Party.
Lo que entiendo es que no se podría forzar a empresas a que liberen o muestren su código, aunque la licencia les obligue. Esto es, podrían usar código GPL, modificarlo y nunca liberar los cambios.
Aunque esto huele a que muchos estados piden a cierta empresa que fabrica cierto sistema operativo a que les muestre el código (o parte de él) para asegurarse que no hay cosas raras y lo pueden implementar en sus gobiernos, y con esto se blindarían.
