I believe it does: "Retaliatory action isn't seen as an inconvenience against the customer, it's a middle finger to corporate. You treat us like shit and we're going to make you feel it too, proxied through customer complaints about broken or missing items"

As a customer, if my box arrives smashed I am angry. If my box arrives smashed with a "Fragile" sign printed on it, I feel insulted. I guess in the second case the complaint is going to be worse and the reputation of the shipping company damaged even more ("They can't even deliver a 'fragile' parcel properly")
