How can this be surprising?

If you identify, contemplate, and sometimes activate an attack vector against rivals, how could you possibly be dumb enough to leave yourself exposed to the same attack?

Also, note that China has blocked this attack vector from the US.

So how colossally dumb would it be for the US to not reciprocally block this attack vector from China?

Hypocrisy is irrelevant. Attack vectors are real.
