Editing their comments (which was a wave of fuck you spez pings) was a personal tantrum. As a human being, I could sort of get where it would seem mischievous and justified to go and throw it back at someone else. Awful judgment, huge breach of trust, but understandable from the POV of someone who just wants to be petty and immature for a moment. I can relate.

As part of a broad pattern though, he clearly has issues veiling his annoyance and contempt for his own users.
