My read on this is that we did accomplish something for all time. We established that we matter. "We" meaning the larger we, not wikipedia google or any player, but the real body politic.
SOPA & PIPA are not dead, but they are in the long grass. ACTA it appears is going the same way (hopefully) because the European Union now includes countries who in living memory have experienced what it means for ones life to be controlled by nameless bureaucrats. The mass uprisings against ACTA in those countries reminded the Germans of their slightly less recent past, and that may or may not be able to tilt the balance.
We need to keep a keen eye on all three, and do what we can to finally tilt ACTA decisively over.
The law where we can do most good though, right now, is OPEN. We need not wait on events to unfold. Today we should focus on educating people that it is not a better written, more moderate law than SOPA or PIPA, but is in fact much worse, more draconian. Educate people about its flaws, and tell them to keep an eye on their legislators, so that if they make even the slightest move to make OPEN a reality, they will hear from somebody. And it will be those same people who got the lawmakers attention the last time. We.
