Saw this comment too late, sorry. Yes, that's overhead for the operator of the service. But this is not what I was referring to, nor the OP to which I answered. He made the false assumption that the gas fee moves up or down because node operators in the network reflect the costs to settle a transaction in the price, if the costs to them goes up then, he assumed, gas fees go up. This is not how it works. Node operators don't have a mechanism to reflect the costs to settle a transaction in the gas fee. Those two prices are allowed to float independently, then there are some mechanisms coded into the protocol that tend to produce equilibriums so that there is never too much disparity and the network remains profitable.
