It's just evidence-free conspiracy babble and you're making it worse by mentioning Snowden in a misleading attempt to imply they're working with rather than, as Snowden showed, being attacked by the NSA.

The win comes from deploying it on the same physical network but you'd still want to firewall it like public internet traffic.
