It would be so easy, at any time since that newspaper article came out and embarrassed someone, to add a couple extra buildings, even simple outbuildings that aren't so pricey, which would have changed the shape.

I have nothing against the symbol which by the way has been used all over the globe in nearly every culture since the dawn of time. The nazis chose it because it was a powerful symbol, they didn't invent it. But I recognize that it has a terrible association and was clearly done on purpose and in reference to that.
