The files have been recovered and are being decrypted as we speak. I believe they will prove to be relevant to our interests.
I don't know why you are so obsessed with the Zoner group known as OSI. They are a free corporation, and as such, trade with whoever they want without being forced by a government. They are not the first group to deal with the Gallic, and probably not the last. Moreover, we have little to no contact with them. Now, if you think that these proofs may still be interesting, feel free to provide us with them.
However, you will need to find another "compensation". We will never, ever give anyone our weapons blueprints, be it gunboat or fighter guns. That, and you would be unable to reproduce them anyway. The sum you proposed is also almost insulting. Really, 500 millions for the blueprints of the most advanced technology in Sirius ?
You'll have to think of something else.
