I beg to differ. Is it a org-wide policy at Facebook that the relevant product / operations head respond to criticism leveled at Facebook in private forums? Are employees required to proactively defend their decisions, on private / public forums? Is this the raison d'être for PMs at Facebook? The reason I'm curious is that I have never seen a Facebook employee ever admit a flub here on HN. They mostly surface here to reaffirm the company position. I don't know if the employees realize it or not but for the most part, this kind of spineless defending - and I have observed it on more than one occasion - appears to outsiders as virtue-less boot-licking. I hope that the Facebook employees know that they are allowed to have differing and contrasting opinions. Just because their founder doles out hundreds of millions of dollars to nameless causes and charities with unaccountable outcomes, does not mean that his every strategic move is unimpeachably virtuous, made with the best intentions of the user-base in mind. Forsaking their reputation to salvage their founder's self-serving acquisitions might seem great now. But these kinds of self-inflicted character-assassinations are bound to haunt the careers of the employees, in the long run. I would advise Ms.Zhuo to think twice before coming to the defense of her founder especially in such nakedly crony-corporate-land-grab decisions, especially when she knows full well this kind of thing is indefensible and not in the interest of the public.
