Commenting in a thread on Politico article on NSA spying and Edward Snowden: 

He isn't giving anything yet to China and it might be that he won't give them anything. If the Chinese government is wise, they just give him a security detail and let him freely meet every possible journalist that wants to interview him.

That would hurt US more than any extra detail he could give to the Chinese and it's hard to think that there wouldn't already be any Chinese spies among the 1 million employees, contractors and subcontractors working for US intelligence services, NSA included.

I would guess that NSA probably has enough moles so that other major states like Russia and less major states that are interested of spying US - like Israel - are pretty well aware of what NSA is doing.

No wonder that Russia, China and in less extent EU are so interested of having their own internet capabilities and constraining the activities of Big Tech allied with US government in the spying.

That of course also means that if US government is ready to pay a price big enough, then Snowden's likely B plan (cross the border to China proper seeking protection there) might not be worth much to him, only to the Chinese.
