I really don't get this mentality on slashdot that DDoS is civil disobedience. It isn't. It's censorship. A sit in allows the speaker to still be able to speak, a DDoS on the other hand is like the gestapo coming in and taking you away because you said something they didn't like.
Wrong and wrong. The entire point of sit-ins is to be a denial of service attack. Look at the lunch counter sit-ins of the US civil rights movements. Yes, the point was just to sit there until they were served -- but in doing so they were preventing other customers from being served as well. Two people at a sit-in is not a DoS; twenty people is. Same here. A dozen Anon members could hammer the site all day long and nothing would happen -- the DoS only comes with a large mass of people. Even a public march is a DoS attack if you have enough people -- as they've gotta block off the streets.
And the difference between a protest and censorship is that a protest requires constant, mass participation. You can't just DDoS any website you want at any time all by yourself. Gestapo censorship would be one guy showing up with a gun and saying "don't print this" and if you do print it you end up in a labor camp. In this case it was not one guy, they were not armed, they were not subverting the normal system in any way, and they have no power to throw you in a freakin gulag. And the duration of their attack is, at best, as long as the shortest attention span in the group.
