And that “$10 connection fee” makes perfect sense for covering per-user administrative costs. The cost is the same to send a $1 bill or a $1000 bill to the customer; a per-user fee to cover that administrative fee is not unreasonable.

But they aren’t talking about administration. They are talking about infrastructure maintenance. Infrastructure is a shared resource, and the maintenance charges scale (primarily) with total consumption, not per-user.
