Tor Project's "Sponsors" page may not accurately reflect funding sources disclosed in Financial Statements
The Tor Project's 2012 Financial Report from https://www.torproject.org/about/findoc/2012-TorProject-FinancialStatements.pdf notes that what appears to be Tor's largest single source of funding is a $876K U.S. Department of Defense grant obtained via the Stanford Research Institute that's described on PDF p.11 as follows:
"U.S. Department of Defense Pass-Through from SRI International Basic and Applied Research and Development in Areas Relating to the Navy Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance".
Despite this (welcome) financial transparency on Tor's own website, Tor's "Sponsors" page at https://www.torproject.org/about/sponsors.html.en currently lists its largest donor as "an anonymous North American NGO."
Per Andrew's response (https://lists.torproject.org/pipermail/tor-talk/2013-August/029640.html), I have submitted this bug report.
