Unfair to whom? It'd say it's more like PTSD.
I have mentioned this in the past, on HN, though much more briefly, and was attacked for it. (Though this was on a previous HN account.)
I don't consider HN to be a very receptive environment, especially if you're saying anything perceived as "negative" about certain companies, including Amazon, Google, Facebook etc. Though it varies widely, of course.
A bit unfair, don't you think? There have been several HN threads about Amazon in the last few months where former employees chimed in, and nobody has been maligned for it.
