Sure, that's far from unanimous, but "widely disapproved of by the general public" doesn't seem like a terrible stretch.
On the subject of polls, this article also shows the meta trends that this discussion is a part of: http://fivethirtyeight.blogs.nytimes.com/2013/07/10/public-o...
FTA: All three pollsters asked their respondents how closely they had followed the NSA issue, and all three found just over a quarter of Americans following the issue “very closely,” while they found from about a third to half not paying close attention at all.
So, how could they report 90% or more of the public with a meaningful opinion about the NSA tracking program? The answer: They all used a “forced-choice” question format, which pressures respondents to make an on-the-spot decision, regardless of how committed they might be to that view. Thus, many people with no real views on the matter had to come up with one, and were thus highly influenced by the priming they had undergone during the interview itself.
Look at the situation Snowden faced. You have a system that widely violates basic privacy rights, based on a secret interpretation of the law, approved by a secret court that only hears the executive branch's arguments and which almost never refuses to grant a warrant (i.e. it is a rubber stamp), with oversight by people who are chosen by the executive branch and who work in secret. These programs, conducted in secret, are widely approved of by the government and widely disapproved of by the general public. Had Snowden accepted the rules and the law, these programs would remain secret and would have continued unopposed indefinitely.
The rule of law does not work when laws are kept secret from everyone. Healthy societies need everyone to follow the law, yes, but they also need for people who recognize failures of the system to stand up despite laws that forbid them from doing so.
