“The NSA’s sustained attempt to get around encryption calls into question many of the technologies people have come to rely on to avoid surveillance. One indispensable tool is Tor, the anonymizing service that takes a user’s Internet traffic and spits it out from some other place on the Web so that its origin is obscured. So far there’s no hard evidence that the government has compromised the anonymity of Tor traffic. But some on a Tor-related e-mail list recently pointed out that a substantial chunk of the Tor Project’s 2012 operating budget came from the Department of Defense, which houses the NSA.”
