You are right, but just that as a society we should stay vigilant in detecting and stopping companies that make profits using ways that are detrimental to society, the same should apply to politicians and security forces. There are checks and balances for that in a modern society, but they can't be watertight. One can only hope that society will feel the "pinch" (as you called it) early enough.
I guess where my metaphor breaks down is that as you said Corporations are constrained from doing things detrimental to society (at least in theory), and the way we constrain them is via law. Security services and politicians are harder to fix, given they make the laws. The only true influence on their behaviour is public opinion.
