There's no protesting or even as much outrage as there should be because it's not a very interesting leak. There's not even a group being victimized (like hispanics or conservative 501c4s), it's something that affects everyone equally.
It's not like people are being inconvenienced like by the TSA, basically it's an out-of-sight, out-of-mind situation. Furthermore, most people probably expect the government has been doing this all along. If you watch CSI/NCIS they use information like this all the time without warrants so people believe that as much as they believe the government can scan photos and match/identify faces.
We're not going to see any change in congress - back in the Bush administration when the secret NSA rooms were discovered in telecom buildings, the same issue came up and latest went away. Due to our poor election laws, the only alternative to a centrist Democrat like Obama is a right-wing nut job who would take the same actions (probably go further).
