Maybe "irresponsible", but more importantly, are they accurate?
I'm inclined to say yes, they are.
You know all those copies of American technology, or stuff that looks very similar?
You don't get that without breaking into a few networks or taking the design documents otherwise.
But what gets me about these reports is that the US is just as bad.
You don't think that the US hacks into and steals Chinese secrets? That the CIA doesn't conduct espionage in cyberspace? That American companies steal industrial secrets from Chinese ones?
We seem to forget that the US is number one in spying on other countries. They've had lots of practice peeking at the USSR's advancements and knowing exactly what they're up to. And those people who have made that happen haven't retired yet.
So if you believe for one second that the US doesn't have its hands in Chinese R&D labs and defense contractors, manufacturers, etc., you're sorely mistaken.
The US can cry all it wants, but the truth of the matter is that they aren't as guiltless as they want you to believe.
