You're conflating two things here. The United States, despite it's many flaws (one of them being surveillance) has a pretty sterling record on freedom of speech. This predated the internet, and has survived, possibly even strengthened, in the face of a massive proliferation in the average person's ability to spread ideas and (mis)information.

You can rightfully criticize the surveillance state that has arisen, but it's just wrong to try and paint freedom of speech as an offshoot of that. Or even, frankly, to criticize the US stance on freedom of speech (unless you think it's too broad).
