So, it may shock you to learn this but uh, people were fighting politically-empowered Nazis for a very long time before the invention of the IPhone. I assure you, nobody in the Dutch Resistance was using Signal.
So when you say "you're shitting on our ONLY method of fighting back" you are A) speaking emotionally in a way that has no bearing on the facts and B) demonstrating you haven't thought this through very well.
