As much as I want to be sympathetic, if I was his co-worker I would feel very publicly harassed especially when the co-worker explicitly was conferring to him privately. Sure shame the monolith that is FB, I would even say shame Zuckerberg he controls the place. But don't shame a fellow engineer who you work with, he didn't have any say in what FB was doing. Also long term ineffective, if you promote a culture of shaming private conversations, then nothing happens because no one talks.
