I'm having trouble connecting your first sentence to your second. It sounds a little like saying "so, the US army has M109 Howitzers, so maybe they'd be interested in this 3D-printed zip gun I just made."

I'm not talking about the vulnerability that this kid found. I'm talking about vulnerabilities that would allow access deep into the Facebook infrastructure. I think there are in fact some vulnerabilities the NSA would be willing to pay more than $10k for if it would allow them long term access to a lot of sensitive Facebook data.
