We agree to a contract of carriage when we purchase a ticket. This includes limits on baggage allowances. We expect the airline to live up to their side of the contract in every way and seek restitution when they fail to do so. Yet, some of the same people here are perfectly willing (and indeed brag about their attempts) to completely violate their side of the contract by means of deception and potentially criminal activity.

So yes, it is pretty "black and white" to me. The "why" of the discussion is an entirely different story for a different thread!
