I don't think these ideas need to be a binary choice. Some amount of redundancy may be beneficial. Strong anonymous communication is desirable when trying to defend against the state but at the same time if it's accessible and anonymous I'd argue it has the same vulnerabilities as Facebook or Twitter currently do with regard to being a non-obvious (to the layperson) propaganda tool. On the other hand, a state sponsored system runs the risk of being used to suppress dissidence. It could be argued that having both and simply paying the cost of redundancy might be a good idea. I don't know if it's the direction I'd argue for, but it's the first thing to come to mind as an off the cuff solution.
