I'm not sure it needs to be effective at influencing the decision making in order to be worthwhile. I think people owe it to themselves to evaluate the ethics and morality of their work, and not contribute to things they do not want to be part of. Take IBM and the Holocaust (https://en.m.wikipedia.org/wiki/IBM_and_the_Holocaust https://en.m.wikipedia.org/wiki/IBM_and_the_Holocaust) for instance. Could you imagine having written that software on your conscious? Would you be willing to write it? I wouldn't.
