My point was, if I have to be concerned about privacy (in fact I actually am, see above) why should I fear about a foreign government while my own one is without any doubt more interested in knowing what I think? Of course should one day I become an important public figure, or a key person in some critical environment, all the data about me would suddenly become gold; that's a very valid point by another commenter. Of course my post was from the point of view of someone who doesn't plan, nor could even choose, to become one anytime soon.
(1) hence my comments where very often I argue about closed device drivers and blobs, which are the best possible place for planting spyware.
