Except that the comment at the head of the thread was the one arguing that two wrongs make a right - that if the US does this, then all of a sudden China could start doing the same thing to US companies. The reply is just pointing out that this ignores the fact China already does this, on much vaster scales, and has done since forever. (Given that China is about the closest thing we have to a second superpower, this fits interestingly with your argument.)
