Isn't this the fact that NSA has access to the internet companies private key for the SSL certificate? There by giving them the tools to decrypt the initial TLS handshake and then from there you can get the symmetric key and decrypt the rest? Or is there more to it, reading the article I didn't see any hard proof of this.
