It does not. This stuff gives argument that Snowden went over to FSB long time ago and that the whole thing is a Russian op a lot more weight.
Also depth of Russian penetration of security services and media in Europe.. in many places it is quite complete. It would not actually be surprising at all if Spiegel had someone working for FSB/GRU.
Having said that it is not 100% certainty. If he was not turned before the disclosures then US whistleblower witchhunt that drove him into arms of FSB is even worse because he really had no choice once US started hunting him.
It just doesnt hang together that Snowden is a spy for me, whether or not you approve of what he did.
Who knows what his motivations are, they very well maybe noble. Enemy of my enemy is my friend kinda thing.. and when you face US gov power you need powerful friends. He saw what happened to other whistleblowers.
In the end whatever the story is I think he did a great thing for the republic in the long term.
