I don't think you're being very clear. The victims of terrorism generally don't have access to the information that these counterintelligence operations obtain. In other words, the victims are in the same place they were before they knew what the NSA was capable of. What I think you're saying is doublespeak. To paraphrase your argument, "Snowden is doing damage to our counterintelligence capabilities by releasing this information. Also, Snowden isn't doing any damage to the government." These statements contradict one another.

My point was that revealing CI techniques empowers terrorists, which tends to be a bad thing for (potential) victims of terrorism.

That's certainly a possibility. The contrary may prove to be true as well. For example, if I was a terrorist and I knew that the NSA was spying on all my phone communications, I may elect to not use a phone. This means that I'm not as effective at communicating with other terrorists which may reduce the effect I have. You may very well be right though. It's unclear to me.
