All your corporation-evil links fail because they do not show that any law requires this behavior. Please actually answer my question rather than other questions which I did not ask.
Your NSA link fails for two reasons. First, anyone can access your data without a search warrant if they do it illegally. It is deceptive to suggest that the USG can legally access your data without a search warrant. Second, as a technical matter, the USG can intercept communication between Google and you, but does not have access to Google's stored data. The concern is over the data that is going to be stored since obviously that communication between you and Google was going to happen anyway. DDG is no more safe from this attack surface than Google except inasmuch as they offer SSL search, which Google offers as well.
