The thing is that in practice, if China knows my secret, they can't do much with it, first because I don't criticize China (I don't live there, I don't know there, why then ?), and the second, is that it is a rather isolated world. Unless you speak Chinese, they don't really care about you. So it's in some way "safer" (unless they resell the data to americans or israeli companies for 'advertising' purposes)
