In french and french derived copyright law, you can not resign all you rigths. "The moral rights are inalienable, perpetual and inviolable" : https://en.wikipedia.org/wiki/Copyright_law_of_France#Moral_...

Which is exactly what djb says about Germany. It doesn’t affect public domain status.

Hum, it feels to me there are subtle differences between German and French law. Notably, the right of withdrawal and the respect of the work's integrity go beyond German law.

In French, a piece of work is not "put" in public domain but is said to "fell". It's not something that needs doing, it's something that happen at the right time.

Anyway, I'm probably wrong since I'm not a lawyer :-)

That's what he says, indeed. What he failed to provide, though, is proof.
