As does China, Russia, Israel, England, France, Canada, Australia, New Zealand, Singapore, and pretty much everyone else in the first world. What's your point? Comparing the actions of nation states to criminal enterprises, while fun, isn't really valid, especially when it comes to prosecution.

The problem here is that it is US who decides whether a foreign person is a criminal or not. The laws can be different in different countries and as I wrote above, posting a picture of Allah can be legal in one country and a serious crime in another. People even were killed for publishing such pictures.

The problem here is that a Russian citizen targeted and hacked numerous US based computer systems. If an American citizen was hacking Russian computers and was caught in China I'm pretty confident that person would end up in Russia. I don't think you're being realistic here. Sure, differing laws can be an issue IF they aren't covered under the extradition treaty between the two countries. How can you not see this?

From a point of view of victim I see no big difference between actions of nation state or a criminal. Should not they be treated equally?

Sure, they should. But they aren't. And I don't believe this case will be the catalyst to change the status quo.
