I remember news about ACTA, people got pissed so many things were done in secret.
The thing is that it's not that if SOPA passes the world changes instantly, but it paves the way for a slow change. Each change won't affect your daily life, but cumulative it will take freedom away from you. That's why each and every step in the wrong direction needs to be stopped.
I don't think we should ever give up fighting for our freedom. Considering the internet is more a wild west than a civilisation it's impossible to control. Each and every law will be met with counter measures to work around them. This means the laws are ineffective in stopping whatever activities thay want to stop, but the rest of the internet will suffer from it. If we don't act we'll end up with an internet ruled by media or other corporations with money but with the "pirates" being the ones who are actually free.
Does anyone remember windows XP? Runs better cracked than legal. But I'm now with linux anyway. I hope that will be a general trend, screw big corporations that do it wrong.
