When contributing to some of their projects, the FSF requires you to assign the copyright to your work to the FSF. As I'm German, I'm interested in whether this is compatible with German law.
German copyright laws states (§ 29 Urheberrechtsgesetz):
(1) Das Urheberrecht ist nicht übertragbar, es sei denn, es wird in Erfüllung einer Verfügung von Todes wegen oder an Miterben im Wege der Erbauseinandersetzung übertragen.
(2) Zulässig sind die Einräumung von Nutzungsrechten (§ 31), schuldrechtliche Einwilligungen und Vereinbarungen zu Verwertungsrechten sowie die in § 39 geregelten Rechtsgeschäfte über Urheberpersönlichkeitsrechte.
This roughly translates to:
(1) The copyright is nontransferable, except via inheritance.
(2) Concession of usage rights, agreements under the law of obligations, agreements to {utilization, exploitation}¹, and the legal transactions about personal copyright rights ruled by § 39 are permitted.
§ 39 is:
(1) Der Inhaber eines Nutzungsrechts darf das Werk, dessen Titel oder Urheberbezeichnung (§ 10 Abs. 1) nicht ändern, wenn nichts anderes vereinbart ist.
(2) Änderungen des Werkes und seines Titels, zu denen der Urheber seine Einwilligung nach Treu und Glauben nicht versagen kann, sind zulässig.
It roughly translates to:
(1) The bearer of a usage right may not modify the work, its title, or author's designation unless agreed upon differently.
(2) Modifications of the work and its title to which the author cannot deny agreement in good faith are permitted.
So you cannot give your copyright away whilst still alive. And even if you die, you can only give it to people you can bequest stuff to.
Given this situation, does the FSF not accept contributions by Germans? Does it apply any legal trick? Does it still require copyright assignments, hoping to be able to enforce them in different countries, even though the German contributors were not actually legally able to give their copyright away?
One legal dodge I came up with is to just not tell the court or the entities they sue who the original author is, just that they got their copyright. But this would likely not work as the court or the entity they sue could request the copyright assignment signed by the author which states their name, letting the defendant know the author's nationality.
¹ Idk how to translate this. It's a bit more than utilization. It's what media companies and publishers of books do with the songs, movies, or books they control.
