It's more important that a government can't spy on its own people. Without equal transparency between people and state, there's no way that the people can change the government. Mass surveillance invokes fear in the people to have and share ideas the government doesn't like. I think anything that protects freedom of speech for the American people is still a win for international folk as well.
