It isn&#x27;t. I also fail to see what it has to do with the discussion at hand. The issue IMHO is not that CMU did research on Tor, or that the US government paid for research into the security of Tor, but the question if the FBI basically outsourced investigations to researchers, and if yes, on what legal basis this happened.<p>Yes, that they succeeded to collect information is a failure of Tor and makes it less trustworthy, I don&#x27;t think that&#x27;s contested by anyone here.<p>Attacking real users in the process of finding security bugs and how to deal with captured data is the (separate) ethical issue here.
