A savvy customer should. If 90% of the bill is Comcast, I'm going to negotiate with Comcast. If 90% is municipal fees, I'm going to call my city council.
In my area we have small shopping districts that have their infrastructure funded through a 1.7% sales tax on every retail business. Best Buy doesn't change the price of the iPhone 14 to reflect this. Should they? I don't know. Instead taped to the surface of every checkout is a typed note informing the customer of the improvement fund. I think a good compromise would be to allow advertising to remain how it is, but require a full detailed bill at the point of sale.
But at least I can see the final price before I choose to commit to buying the item. Many ISPs won't tell you what the bill is going to be until they've already wired you up for service.
