The press was selective in what Snowden released. As far as we know, Snowden wasn't selective in what he obtained, or in what he then provided to adversary intelligence services in China and Russia.

I don't like what Snowden did, but I would respect the hell out of him if he had decided to stand up for his convictions and face the music. He'd have had a far better case, and would have had incredible EFF and ACLU lawyers on his side, and a ton of public sympathy. Instead, he turned an act of patriotism into an act of espionage and treason.
