No, Facebook/Google engineers should consider their actions carefully and do what they think is right. In fact everyone should. I'm happy to oppose SOPA but I'm not joining a mob.
Look. I am personally against mob mentality in most scenarios, but given the current circumstances I honestly believe that the formation of a mob aligned in opposition to this bill is exactly what is required. Due to this issue's nebulous technical nature the folks in charge and the general population have an unconscionably limited perspective and there is little to no real awareness of the proposed act or its potential consequences in the collective consciousness. SOPA should be immediately halted with extreme prejudice and the real issues should be thoroughly reconsidered in an open forum with policy makers, entrepreneurs, experts, and citizens working together to create a legitimate policy that is levelheaded and forward thinking. Beyond the minority of us who are actually clued in to the guts of SOPA and it's consequences there is no genuine geography of dissent. Shame. In other words... Aunt Trish needs to have a day without facebook so everyone will start actually talking about this stuff.
No, they should be patted on the back for not being rash.
A SOPA blackout by Facebook/Google would show just how much political influence they have when they decide to abuse their position. Once that's made clear governments around the world would quickly act to remove that power by various new laws and regulations destroying both companies.
