I understand that for non-US citizens, there's nothing much we can do about it. Which is frustrating because I know this will affect the rest of us if it's implemented.
Yea, if Twitter, Google, and Facebook shut down for a day in protest, it would definitely cause waves.
I'm fairly confident in saying that if they did that for 24 hours, they wouldn't lose people, but would in fact raise awareness about this bill to an unprecedented level that no media icon could ignore or be condescending towards.
