The CIA should not be treated as the 'enemy' for you guys: they are a neutral party. You can speculate all you like, but at the end of the day someone wants to pay our lead developer some cash in exchange for an education in the protocol: that can only be a good thing in the short term. In the long term, if the CIA "were" an enemy, they could find this all out anyway.
I don't entirely disagree with your sentiment but... this is the CIA we are talking about.
We are talking about the people that have done everything from setup secret brothels to study what happens when they slip people LSD 40 years ago, to helping run secret prisons and torture facilities, run guns, introduced crack into inner cities... and regularly murder people with remote controlled planes.
The CIA is, in my estimation, the enemy of all civilized human beings.
