Would you rather have a friend or an enemy spying on you? That appears to be the only options now that technology has thoroughly penetrated every day life.
Another point not mentioned enough is that societies with free press are far more likely to find and report exploits/backdoors. In a country like the US you see this a lot. There's many cases of security researchers reporting possible government funded exploits against their own government. In a place like China reporting something like that would probably mean you disappear
