At this point, there are numerous things happening such as laws, inquiries, public debate, and policy changes that are all due to Snowden's release of information. I feel that he has brought to the forefront an important issue and revealed things that the public needed to know. I can understand to some degree that people don't like how he did it, but given the machine that is the government, I don't doubt that this was the only way to bring about such changes (or at least debate and knowledge).
After a bit of a cool down period, I don't hear nearly as much hate for Snowden. Libertarians, Republicans, Democrats and all other flavors should want a more open government. The government does also need to keep some things secret. This gives them a reason, the means, and a public grant of power to keep things from public knowledge. Some times the only way to circumvent that power is through a leak/whistle blower.
As far as this story, the public needs to pressure the government to keep no more secrets about Snowden. The cover of endangering certain sources or resources is no longer being accepted as we have seen little damage and much good from the release. It's time the US Government come clean and it's time we tell them that we demand it.
