Most of what he leaked has nothing to do with the government spying on its citizens. Most of the documents relate to how the US deals with its own international interests and how it protects those interests - right or wrong.
For this reason, he's not a patriot or a whistle blower. He's just another government employee who stole and released a ton of classified documents that did more damage to his own country than what he's been telling people about the NSA spying programs. And let's be honest, it was something most people already knew about anyways. His documents only confirmed a lot of what people already suspected. The only difference was his documents showed how deep the rabbit hole went.
In a few more years, nobody will care - let him rot in Siberia for all I care. All he did was weaken a country by his actions.
