It's not that simple. For international shipping, many model manufacturers simply don't include it on the art, have the swastiks literally cut out (by hand) from the decal sheets, and have their own special "export to germany/europe" versions. You're trying to force a topic that is other than what I am talking about.
I am not discussing the illegality of the swastika in Germany.
I'm not discussing it's censorship/absence in many types of artwork on model boxes or in model decals or internet artwork.
Specifically, the practice of obcsuring it with a big black diamond shape is very recent.
You can also look and see hyper-paranoia kick in when some companies censor the boxart of Finnish craft (mostly Japanese companies, again seems to be a trend with the sources), by turning the roundel to a while field with a blue "+" sign.
You're not grasping the point. It's not that there has been censorship, it's this type of substitution is a recent trend.
I can't explain it any clearer, and if you don't get it I'm just going to move on.
