Whatever you may think of the guy, and he's not great I know,
I would argue that extradition does not make sense. He's a Finnish German national, living in New Zealand and headquartered in Hong Kong.
How does he have to stand trial in the USA? He's not American, the business is not American. He doesn't live in America.
If you say his customers are in America, we sure, and Ebay has customers in Saudi Arabia, and China.
If you argue that he broke laws in America. Then you have to except that the head of Facebook or Ebay or Google could have to be extradited to China or Saudi Arabia or wherever because they broke the laws there. Not a great precedent.
The case should just be thrown out.
