The ABC’s are staffed with arrogant people - some deservedly so, but arrogant nonetheless. They see Maidsafe’s work as incomplete and so haven’t done much to even develop counters for it yet.
Tor has been around a long time and I2P is out there and better than Tor for security but not so good as an out-proxy system … then there is freenet - super secure, super sluggish, and more recently zeronet … basically though these are all fringe and not a huge threat to the status quo.
I expect they envision Maidsafe’s efforts to be of the same or similar quality and that in the end it won’t attract the kind of attention needed to be a threat.
So, sure they will develop ways to attack it down the road (it has to be completed first) and I’m sure they written up a few reports on it and the team and those are sitting in a stack of reports on some administrators desk.
Understand that Statist government is highly bureaucratic with many higher priority (more political) items/agendas on their plate … they also don’t move anywhere near the speed of technology.
In short, don’t worry so much. The tech is open source and on the web - so it’s not going away. In time, it will reach the level of security required to achieve the goals of it’s founders and supporters - as we will all keep pushing it down that path. The ABC’s can only slow it, they cannot stop it and at this stage it’s just a tiny blip among many on their radar.
