The ISPs are asking, explicitly, to be allowed to quote a "maximum possible" price inclusive all fees, non-itemized, like you suggest.
> No, they can't --- the fees are different in neighboring municipalities.
So? Who cares? Why do I need to know this as a consumer? I'm sure a McDonald's in the city pays higher rents than one in the country, yet both will sell me a coke for $1 without ever making me think about that fact.
> There isn't one single all-in rate they can charge everybody who walks in the door, which is the whole problem they're complaining about.
If the current pricing for a 100mbps Internet plan is $40 + $1 (local tax) in one town and $40 + $3 (local tax) in the next town over, the ISP is welcome to just create one label for that plan at a $42 price point (with no enumerated taxes/fees shown at all) and abstract away the computation/remittance of those taxes internally. Call it $45 to really play it safe. Sucks for the people in the lower-tax town, but this solves the problem the ISPs are crying about.
