I think you misunderstood what I said. The comment I replied to expressed the myopic view that stealing trade secrets and corporate espionage is a one-way street.

I'm fully aware that pretty much every nation uses it's capabilities to get an advantage, through any feasible means - that includes corporate espionage. I highlighted the Snowden leaks because they exposed the NSA's activity in that space, in response to a comment that painted the picture of "only the Chinese do this" and "it's a one-way street".
