Not sure where you see a case of shoot the messenger. This messenger delivered a message that no one asked to be delivered. Let's say your son asked his girlfriend to marry him and instead of getting the good news from him, you find out from someone on Facebook you don't even know. For those of us that call @Tango friend, this was inappropriate. I don't know how @Tango feels about it, but I was pissed off for him.
I understand your point and appreciate it. My sympathies to Tango.
