I do think Snowden harmed the US somewhat with the leaks. By revealing what the government is doing, he made the US less popular with the world, and made companies and foreigners (and US citizens) less willing to do business with US based companies, for fear of the NSA. In the medium/long term, I have little doubt that Snowden helped the US, but short term, it is reasonable to say he did harm.
