> Surveillance != censorship

I disagree. People under surveillance self-censor. A recent study showed journalists censoring themselves in response to surveillance (i.e., their communications). Another showed that people's searches on search engines (or maybe just Google) changed after revelations of government surveillance.

It's not an accident. It's a well-known phenomenon and a method of intimidation.

(Sorry I don't have time to look up the details of those studies.)
