Something to think about is that this is a first occasion for the event. Even if SOC can't get the word to tens of thousands of fans this time around, the word will spread to those who want to be involved via this first attempt. Even if it never amounts to making a huge dent in the amount of red, the symbolic meaning is what matters, here.
All in all, it's just another effort to speak out. Whether it's popular not is to be seen, but its contribution to the whole matters for the movement.
