You ask a fair question. In general, I don't support government censorship, and especially not prior restraint of mass media (such as exists in China today). But I also have trouble characterizing what happened in the case discussed in this thread as "government censorship," inasmuch as the site is still posted for all the world to view (and for much of the world to become more interested in, as a result of this controversy). As another reply in this thread points out, Google's response seems to be standard operating procedure for Google much like what Google does in many other countries around the world. I am not an Australian resident, much less an Australian citizen, so I will defer to the constituents of the constitutional commonwealth that is Australia to decide whether the current policy in Australia is a good idea or not. But I don't think Google is deserving of particular criticism here, and I think the blog that publicized this story might have devoted more time to how Google is spammed up by quacks on medical issues or constrained by dictatorial governments like the government of China.
