well, I say that constant hopes for transparency and the strides we take towards those goals will keep the United States high on the list of nations with decents human rights.
WL is one of those strides, and I think it's invaluable.
It's 'interesting' that given the muck that WL has raked up about the U.S. that anyone could be upset about their ( the US ) having been a target..
You would be naive to take for granted that WikiLeaks is acting exclusively out of principle.
That's where you're wrong. Wikileaks' mission is "transparency for governments and privacy for people". Perhaps they seem to have affinity for publishing things contrary to the US' interests and you're right that the US isn't uniquely bad at protecting human rights, but the US (and Western European sigint community) violates privacy on a scale that's simply unmatched, it's reasonable for them to treat the Anglosphere's sigint as their primary adversary.
I don't know, but I would be surprised of Russia even captured 1% of the data that the NSA captures routinely (or was capturing at the height of its excess).
Additionally, Russia seems to keep quiet about what they do which is lying by omission at worse. A lot of US security officials have lied under oath about what the US is doing - I think it's more important to expose active and direct and popular lies than incidental lies.
