Or a University who doesn't want to get sued / get bad publicity for screwing with a tool used by government agencies...
Legality aside, I'm surprised this wasn't pulled on ethical grounds. Does Black Hat not require "researchers" to follow responsible/coordinated disclosure? What about the political dissidents who use Tor? They could be at risk of certain death if caught by the authoritarian regimes they live under. Without coordinated disclosure, the "researchers" might as well have been signing death warrants.
That's an odd construction...
