Hamburg is a favourite for such cases because they just have no clue about technology. They are just old fashioned.
As a small indie developer, I could not afford to keep on fighting. I gave up. I was a psychological wreck. And since it is not binding, big entities can afford to sue you non-stop.
Hamburg was the second time I was in a court. I got sued by the same big corporation. I won the first one.
Despite not being binding Sony will use this as a precedent and they will start going against the bigger DNS players, till all of them have to comply with their demands.
