Exactly. Fedex sees the writing on the wall and figures it might as well wring the last cent of profit out of the relationship (and who knows what profit was on it with the contract). In other words if they feel that Amazon will cut them out then what is the motivation to serve them at discount rates? In a way this is similar to a commercial landlord with a tenant that wants to go on month to month. You take advantage of the opportunity and charge more rent for the accommodation. Zero reason for Fedex to not do what is in their strategic interest here it's business.
