Is a Tor developer a "terrorist", or even a "criminal"? If not, then I see this is a serious abuse of power. It's no different than the government spying on anti-war activists and MLK in the past. Yet, every time Obama or any of the NSA apologists come on TV they say "no abuses have happened", and unfortunately many people still believe them. This strikes me as something they do quite regularly, and it's only a small part of a series of other such abuses.
