That's not the point. The point is, how is the US government going to bring a case against a German company based on data they illegally intercepted sniffing traffic? If the data were on US soil, they could simply seize the computers once they knew there was offending data on them, and claim it was through an "anonymous tip" that they caught wind of the illegal activity. If the data is on German soil, they can pound sand.
