i use foss because i like the idea of it (its basically cyber leftism), as well as to hide from western intelligence, since i have the misfortune of living in there. why are YOU using it?
unlike western nations, china is a a dictatorship of the proletariat, aka a peoples state. you will only be targered, if you are some kind of rightist. i happen to support the targeting of such people, to the point that i believe the prc isnt doing nearly enough in this regard, allowing elements like deng xiaoping to rise through the ranks. cuba and korea are much more consequent in this regard.
