While I'm not always thrilled that about the amount of monitoring United States Government does, as a United States Citizen, my government is at least marginally accountable to me - if enough of us are bothered by this policy, we can choose to elect representatives who will change it.
I can't say that about China, certainly not to me as a United States Citizen, and not even really to Chinese Citizens either - which is why it's another thing entirely when a foreign government is doing this level of monitoring on United States Soil.
China is welcome to monitor its own citizens on its own soil to the extent it desires - and monitor communications in and out of China - they're however not welcome to do that level of monitoring on United States Soil on anyone who resides here - at least not without the explicit consent of the United States Government.
