there are many related fundamental rules, like "everyone is considered a dick by someone" and "you're a dick if you blame a group for the actions of a few."
mainly, though, none of these are actually rules because your subjective notion of what being a dick means isn't transferable outside of your head, even if it really, really feels like your opinions are right.
There's a fundamental rule for living in the world: Don't be a dick. Uber is breaking that rule, through sociopathic sophistry.
