Since weasel wording is pretty prevalent on this topic I would note that they could still run NSA algorithms on the dataset and return the individuals that are "hits".
Why was the word voluntary in there?
The title is pretty misleading. Facebook isn't denying anything.
Obviously the NSA doesn't have direct access. They don't need it, and wouldn't want it. If they had it, they couldn't have put together these nice convenient PR packets for times like this.
What the NSA most likely has, is signed assurances of data integrity, and unlimited API access.
The most important aspect to lying, is the intent to deceive, it binds all forms of lying together. What matters in the blanket denials being issued by all the companies, is their intent to deceive. Is it a lie when they say they don't give direct access to the NSA? Perhaps not, but their intent is deception, and that's what matters.
In which case, Facebook are not lying when they say that the NSA don't have access to their servers, but they do have access to their network traffic.
