I just received the following disappointing answer from the Free Software Foundation.
Because even the FSF does not help me and I am a retired old man, who has no more nerves to stand the attacks of the lawyers of a big company,
I finally gave up and removed the Router application from my Freerouting website.
Sorry, that I could not save the Freerouting project for the public from the unjustified attacks of Zuken.
Thank you for your time.

The FSF accepts copyright assignment on software that is becoming a part
of the GNU Project. We do this so as to be able to enforce the license
on the work against GPL violators, not to defend against claims that the
work itself infringes on another work. We have no expertise in handling
such cases, and no resources to deal with such claims either. Our
assignment contract actually requires that the contributor warrant that
there is no claim of infringement against the work, and requires the
contributor to indemnify the FSF in the event that a claim is made. In
short, we could not accept assignment. I'm sorry we couldn't be of more
help, but unfortunately it is beyond the scope of the services that we
