Somewhat agreed. However, there is enough repression to provide incentive for semi-shady people to work on these things. Unfortunately piracy seems to be the biggest incentive for secret communications, and while that is indeed productive, it incentivizes high-bandwidth torrents for large files, which is not exactly in line with the most crucial needs (although of course there are important uses for distribution of videos and photos). An interplanetary low-bandwidth Usenet might be the most crucial necessity for the upcoming dystopian future. So I suggest we start encouraging the spread of subversive poetry and politically uncomfortable discussions, to incentivize such a grassroots network.
