The BBC article is old (since 2018) and I would like to hear what the current situation is
and where is the German enforcement body. What is the document that lifts the ban?

(edit):

Is there a way to contact the USK (whatever that stands for)?

By the way, all my Luftwaffe skins have the swastika in the Photoshop PSD files. It would
be nice and possible (though a lot of work) to update the skins to include the swastika.

WB probably has the last word on this anyway. Hello?

Only talking for Austria: The Swastika (Hakenkreuz) was not illegal by itself, but it was when used to campaign for the NSDAP or its illegal heritage. There are Neo-Nazi groups acting mostly hidden, some in public today. As a reaction to political extremism of any color, Austrian law now forbids certain handmoves (Hitler Gruß, Wolfsgruß etc.) which are used to identifie oneself as a member or a supporter of an extreme political movement.
Swasticas are NOT, nor have they been, illegal on historical displays like museum artefacts or static modell aircrafts.
I did vote AGAINST the display of swasticas anywhere, because illegal or not, it is still a symbol of mass murder and ethnic crime of unlimited dimension. Its not required for playing or enjoying this game, anyway.
Besides, if my wife sees me flying a plane with that symbol on the screen, she will end the session, for sure. If Id see my son doing it, same result.

Anybody know if WB has read this thread/post? The Ju-52 is
ready to .VFC and I'd like to know how to submit the artwork.
