Yes. These are not comparable political systems. In the US, the information you share can be accessed by law enforcement with the approval of a judge if there's a crime suspected. But in cases where the government improperly accesses your data, they actually destroy their own case against you, because anything from that poisoned tree of evidence can be thrown out in court. Even when governmental power is abused in the US, it is nothing like the routine surveillance and suppression that chills free thought and speech in a totalitarian dictatorship like China.
