We live in a world where everyone can know who you are and what you are doing. Think about your behaviors, you don't know who is watching.
Martin lives two lives, the first is someone trying to change the world, the other is a life of mass information, violating privacy for the sake of justice, public shaming with the goal of behavior change, then taking action to change some people's existence. His intent and the consequences lead him down a different path, he is inspired and decides to make a real difference. A difference that was a lot more public and infinitely more discreet in its methods.
