I agree that Snowden's disclosures went too far. But to be honest, that was more on the journalists that released them than him. Ultimately I think it was important that Snowden disclose the existence of many of these programs. In so doing the journalists he entrusted with his materials unfortunately ended up disclosing more details of specific techniques and methods than I would have preferred. However, I think the basic idea that he informed the US public of the types of bulk collection that were going on is important, and ought to be praised.
