Speaking as someone who at work (big corp) has to do semantic loop-de-loops and contortions to sugarcoat even the mildest criticism of sometimes utterly stupid ideas, just to avoid ruffling feathers and be politically correct, I find this refreshing.

I don't find anything but objective summary of what happened in their post. No hostility at all. But that's just me.
