I'm guessing Mozilla's Tor middle relays will soon be a part of PRISM
mozilla, like few other companies, has my full faith and confidence that they would pull a Lavabit and close up shop before letting something like this completely erode their users' trust.
So, silently comply with warrants and other requests until a high-profile case comes along, then refuse to cooperate until a judge gets you to hand over everyone's data and your master keys, then turn that into a big PR show? OK.
