I have read several blog posts of Googlers about their work experience on their own blogs. If leaking unannounced works to the public, that's definitely a standard how work should be treated.
So I'd want to hear more about exactly what's going on. A "spy program" is a catchy phrase to grab reader attention. I think anyone should report if they spot anything against the interest of company such as insider trading, violate NDA etc, especially given Google is publicly traded.
