A cloaking system is not useful if all the cloaks say “Navy” on them. “If you have a system that’s only a Navy system, anything popping out of it is obviously from the Navy,” Syverson says. “You need to have a network that carries traffic for other people as well.” Tor Project was incorporated as a nonprofit in 2006 to manage operations.

Ah - wow, dang. I believed the cover-story that Tor was a side-project of a humanitarian org in the US gov that wanted to provide people in firewalled countries a way to access the wider internet - of course, Tor does do that (just as a nice side-effect, and to be fair, the US does benefit and encourage democratic (...and neoliberal) ideals worldwide as its in their own interests to).

...it's kinda like how we were all told that the 1950s-1970s space-launches with monkeys and other animals in them were for bio-scientific experiments when they were really just cover stories for launching spy-sats and military satellites.

To be clear, they encourage democratic ideals where/if it's in their own interests to. There are plenty of places where they encourage non-democratic ideals as well (or directly fund their own coups to put usually military leaders they like in power).

The space race was a test for intercontinental ballistic missiles.
