Which is not to say that he wouldn't be burning bridges, but if I were to feel that he was wrong to publish this, I would feel that way on the basis of deciding that he was being mean or petty or spiteful or hurtful.
I guess I just don't see the people he is satirizing as perceiving themselves as being hurt by this deck. It could be a question of timing: I might feel differently about the exact same post if it came at a time when VC's were laying analysts off and we were treated to pictures of employees carrying their personal effects to their cars.
