So lets say I am a retailer. I don't own the product (have a relationship with the person ultimately setting the pass through charges) and I sell the subscriptions to the end user for access. Unless those passthrough charges are made available to me before the customer signs up, I cannot reasonably estimate them when advertising the service. Instead, I can only pass them through when they appear on my invoice, or absorb them. In fact those are the 3 options here. Pull out of the market, pass the costs through (and attract fines) or absorb the pass through fees. Punishing me as the access provider doesn't make sense. Whether or not you have personal misgivings against the access carrier, it seems like the municipality setting the pass through charges should be asked to make them more consistent, or provide an API for lookup. I dont know what the response here is going to be from the retailers, but I am betting its not going to be pro consumer.
