I understand why you say this, but even if they're truly doing the right thing here, I only owe them gratitude enough to say, "Thanks for stopping spying on me, finally, at least in this way." Add that to the number of times the NSA has shown itself to be untrustworthy and intentionally deceptive, and I'm willing to seem ungrateful and hard to satisfy. They've cultivated a hostile relationship, toward fixing which this is at best a small step.
