No I don't, it sounded like an analogy - comparison of different things - you refuted that and doubled down on your stance. Why would I infer sarcasm?

> Increasing the cost from zero to nonzero is a limitation, not a cost adjustment.

That is nonsensical. "Increasing the cost ... is not a cost adjustment". It's not a limitation if you're willing to pay the new cost. Thus, not a direct limitation. It's optional based on how much you value the service. Doing the same to water/electric would just be increasing the rates and letting supply/demand economics take over, you are saying people need to be forced to use less without mentioning any cost adjustment... not clear if you know what a cost adjustment means.
