I've a feeling it may be the swastika law.
I know there are a couple pictures, if not many, on this forum that have a model with a swastika on them. For Germany, one is one too many.
That symbol is forbidden and, maybe, by linking here it is like they are accepting or condoning the use of that symbol. Additionally, by linking here, it is almost like they are just putting the symbol up for view on their own site by providing easy access to it.
I am only speculating and I am sure I will be corrected if I am wrong.
Also, this is a very serious and sensitive subject and is not taken lightly.
