They said they have jurisdiction because the contents is directed (also) to users in Germany. They said nothing about exclusive jurisdiction or exclusively directed to Germany. They also ruled that access to the average user in Germany must not be easy (acknowledging that the user decided to download can circumvent it.) There was not a word about making the contents available to users in any other country.
In the context of existing copyright laws the ruling is understandable. It's just plain nonsense to have contradicting copyright laws in the age of a global internet. And if you say that copyright should only be enforced according to the country of the distributor then you just move all contents to a country that does not enforce at all. But isn't it just the US that complains a lot about (their) IP not enforced in China or Vietnam?
