the whole thing appears to be a privacy tool recuitment thing

People who finished the 2012 round were asked a few ideological questions, such as whether they believed in freedom of information and privacy and opposed censorship, and were told to work alone. Marcus Wanner, a 2012 finalist who spoke publicly, said the group described itself as working on privacy and anti-surveillance tools, and that finalists were invited to a private forum to collaborate on projects in that direction. He said it fizzled out without much happening, at least for him.
