I perceive this as an example why allowing privacy violation for one group for the "sake of greater good" does not work. Usually the same tools will be used with oppressive regimes. In the beginning it will start with pretext that "we are using this tools to find terrorists, pedophiles and protect children" but more often it will end up prosecuting journalist, silencing whistleblowers and undermining political opponents creating perpetual state of oppression and corruption.
