"Because of that pattern change, mission managers can no longer decode the science data beamed to Earth from Voyager 2."

It's pretty obvious what happened. Voyager 2 saw something that the government doesn't want us to know about, so they commanded Voyager to encrypt its transmissions. It's quite possible that NASA indeed can not decrypt the transmissions, but certain other agencies within the government sure as hell can. I wonder what they saw?
