The real problem is that people have been beholden to these monopolies who very obviously don't have their best interests at heart. We are now, thanks to internet and unprecedented levels of connectivity between people, in a position where we can (with a bit of effort, admittedly) take back some control and build something better for everyone.
So that's how I see it. This isn't a knee-jerk reaction to SOPA/PIPA/ACTA (at least, not entirely). This is a call for people to make the world a bit better before the incumbent powers that be destroy our chance to.
