"Freechain" is great. It passes the cognate test (sounds like "keychain," which it is), and the "free" part gives it the multiple meanings of both FOSS and freedom from surveillance. Euphony is pretty high, and it looks fairly low-noise on Google, too.

And chain even retains some connotations to "felon" ... ;-)

Seriously, though, "freechain" strikes a nice balance between being a new term, and hinting at what the use-case is.
