You are looking at it the wrong direction. This is a model where average residential person is paying UPS to deliver all packages they ask for. But UPS has decided that jet.com must pay extra or their packages will be arbitrarily delayed vs amazon because UPS has invested in amazon. Then the customer cries foul because they thought they were paying for arbitrary package delivery. The government tried to say packages should be treated equally by treating the package delivery as the USPS, but UPS has paid off the party members to ensure they can continue to double dip. Also remember it isn't that a given company isn't paying for "priority" it is that they're going to be actively underprioritized unless they pay.
