Freedom of choice
What would you prefer as a head of state - to have computers that continuously transfer all content and records of all your activities to unspecified servers in the US, whether you want it or not or would you rather prefer to deploy computers that do precisely as you please?
What would you prefer as a private person - to have a computer that reports all your interactions to uspecified servers in your country and any other country intrested in your life or have a machine that provides at least a basic level of freedom from unwarranted on-line search?
Saying that you have nothing to hide is like being a person with a complete speach impairment communicating that he is not really interested in the freedom of speech. We really should be.
