Yeah just like all of those people who protested their workplaces by not working. Not only is this pointless, it only hurts themselves because they lost the wages they would have earned. They would be better off working, then sending a letter to their congressmen on their break. These kind of strikes have never accomplished anything. Oh wait a minute...
The problem with this example is that if people stop working then the company suffers, loses money and thus are forced to come to some sort of settlement over time.
Wikipedia goes down and the net effect on the people drafting the bills is....? Well, you tell me...
Passive resistance and strikes only make a difference when they impact the people involved on both sides; wiki being down is going to have no impact on those wanting to draft the bill thus from that point of view is pointless.
For the general 'non-geek' population this is likely to cause an annoyance more than anything; they'll see some text and either ignore it and complain about the site being down or read it, not understand and then complain about the site being down. The population simply isn't well versed enough in technology to realise the problem.
And finally, we get to the point that a vast majority of users
cant make a difference at all. Living in the UK all this 'blackout' is to me is a mild annoyance which ends when I wake up tomorrow. I can do nothing to adjust the outcome of what is going on in the US (and the last time people in the UK decided to voice an opinion on US politics that I recall was back in a presidental election when we basically got told to STFU and keep out of it... mmmm).
In short as bad as I'm sure this is being in another country with no say on the matter I currently simply don't care and just have to live this with mild annoyance. A position most of the users in the world are in.
