Stuxnet was cyberwarfare, not hacktivism. The point of Stuxnet was to disable infrastructure, whereas the point of much of what Anon does is to get attention. Now, granted, that doesn't require the ego-driven hacks and braggery that we've seen from them, it simply requires getting in, getting out, and posting the data anonymously then promoting and publicizing the data, not the hackers. I suspect you may start to see more of the hacker cells aligned with anonymous take this approach in the future to minimize the heat that they feel personally.
