Not directly, though we collaborate with Americans on open source projects - one of the main contributers to Cyrus is based at CMU (which is where it came from in the first place) and of course we run plenty of other software developed by people all over the place!
I don't think Numberwang is interested in our developer's nationalities because of any patriotism/racism. I think the question was more about if any of us can be compelled to compromise our user's privacy by either the PATRIOT Act (no), National Security Letters (no), or some other insane US law.
