Most googlers who are also engineers can find out what most of these things are, and I would expect many are already aware of what those projects are likely to be. It is a core part of our culture that we share information openly within engineering, and don't leak it.

The grandparent comment makes it sound nefarious, and there are a lot of people that dislike the US... but it doesn't sound too bad to me to bid on contracts for a democratically-elected government.
The NSA thing is disappointing and it's important that the electorate hold the government accountable, but democracy has not broken down yet, and the situation isn't quite as dire as, say, North Korea.
(Waiting for the "google employee compares US government to North Korea" headline, sigh...)
