I really respect Clay for this post (though I am floored that anyone would believe Amazon intended what happened), because it's definitely not socially required to apologize or feel embarrassed for being wrong about anger if the thing was bad enough.
The part about people justifying their anger post-explanation is really true and is present in some of the comments on the post. It seems to mean chastising Amazon for taking too long to address the serious situation – which seems code for giving people too much time to make fools of themselves.
People need to slow down and think.
