That's true. Following the Christchurch shootings, Telstra pre-emptively blocked 4chan, 8chan, Zero Hedge, Liveleak and others. (Vodaphone and Optus had similar blocks with slightly differing lists of sites they put in place after Telstra had enacted theirs). They did later lift some of those blocks after everyone stopped sharing the video of the shootings, but not all of them. (And if the government ordered blocks on some of those, I actually would be fairly comfortable with it, if it were done with process and transparency.) This isn't a judgement of whether their actions were morally right or wrong. However, an ISP should probably be pre-emptively calling MPs to make a decision, rather than controlling access directly.
