I understand that the pressure to drive down costs ends up driving traffic shaping. Such pressure comes from customers , competition, shareholders and managers inside the organization. You sell me a product for a price; if I want a different product, the price will be different. BUT I should know and be able to choose what I buy. Don't lie to the customers. PS.: Plus Carriers operate in a heavily distorted market (in most places competition is not free, there is heavy governmental influence and the customer has no choice) so the whole "invisible hand" argument I opened with is debatable.
