"Privacy" probably isn't a keyword that I would search for if I had new concerns about my online privacy. I think "secure" or "encrypted" as in secure browser, text, communication, etc. After reading a few Snowden related articles, I think a lot of people would also bypass simple keywords for more targeted searches such as "TOR", "OTR", etc. Also, as the author makes note of, I'd want to look at search data that wasn't from Bing, mainly because that is the default installed search engine for MS Windows. While anyone may choose to use Bing, its users will also include a large pool of unsophisticated users.
