I'm reading "consent of the Networked" right now. The book is about digital rights, privacy, government and the internet. Once i finish I will write a review for the Urban Times. I found out about the book through TechDirt's book club. One of the major points the author makes about repressive regimes is the activities of pronationalist actors that are not truly part of the government.
These actors are typically regular people and act as hackers, journalists or progovernment rally organizers. They are found in many countries including China, Iran, the former regime of Tunisia and Libya. In a way these groups are a counter weight to "organizations" like Anonymous, dissent groups and the "liberal" media. However, these organizations are unlikely in the US and Europe right?
Well according to the author now. These groups do exist in the US and in some cases are formal business like HBGary. Some of them actually work for the US government and others do with a wink and a nod. These groups help monitor internet users and potential members of groups like Anon. In many cases this extends the impression of continual  observation by the government and other actors, which can lead to self censorship and self selection for activities.
Has this happened to me? You bet it has, but I didn't really think much of it at the time or how it could really impact me. One of the times happened during a Facebook conversation about Wikileaks, which I was supporting. The person I was discussing doesn't like me much and thinks I'm "a rube." He suggested that I should get a job which requires security clearance so I would get an understanding of how things actually work and that I was niave. Of course I disagree with the fact that I'm niave and I view the world in a much more complex manner than his black and white view. However, I had been thinking of applying to a government type position and he told me I should be careful what I say, which he is correct. This then led me to rein in my views and self censor. This had serious implications on how I discussed topics for some time.
The other times are slightly different and after I started blogging. For one my brother is in the Boarder Patrol which gives him clearance and my sister does stuff she can't talk about. So, to some extent, I don't want to negatively impact their ability to work either. This does have a moderating affect as well.
The final source was actually my dad writing to me about my post about anonymous and my discussion of using DDoS as potentially a source of public demonstration on the internet. I was not surprised that he suggested I be careful, he did retire as a Major in the Army Reserves. However, when responding I told him I was already being careful with my wording due to self censorship. I already expect that I'm likely to have my material spring up on someone's radar due to the content I write about. So, I do try to be careful.
In a democracy where these threats should be minimized we have to worry about it. Why should the rest of the world be different or any less oppressive?
