Given the persistent, and intense criticism on HN of all things NSA since the original Snowden reveal, to say that your question is absurd would be putting it gently.
In fact I've seen no other platform that has had more negative + rational + informed discussion regarding the NSA than Hacker News.
To be fair, quite a lot of HN users honestly find NSA related articles to be more noise than signal, particularly when they lack technical details and can have the tendency to spiral into political arguments and blind conspiracy theory. One doesn't need to necessarily invoke the specter of government-driven censorship to explain that effect, given the way some stories can overwhelm the site.
