I do think secret services did more damage than good with their forward surveillance of citizens, which basically was wild west surveillance initiated by states. The lost trust cannot be repaid for decades, maybe even centuries. It basically voided the significance of huge parts of constitutions of many countries that explicitly forbid such actions. This is beyond political realities of realpolitik where the justification was an alleged immediate threat of terrorism. And that is an overall problem. The fears decide the action. So improving security is becoming dangerous, because parents or teachers just putting their children into a cage of complete surveillance is the most probable outcome. Because the ambition is to get more control. But that doesn't provide much security at all and creates even far greater threats than the "wild west" free open net ever posed in the past.
