Ah, the sweet, sweet sound of sinophobia. There's a better chance of the CPC accepting the research and altering the design than there would be in a capitalist country, I can tell you that much.
If there's no oversight of tech companies, this is just what they do - they think they're adding features that will help them compete, but since they don't have a security focus, they rely on obscurity.
Do the per Capita calculation. Why can US and Canadian folks emit 4x as much as the average Chinese citizen? Do you believe you have the right to do so only because you are born in the West?
I believe that if it wasn't producing shit for US its emissions would be vastly lower.
