No they don't. On a used sale, the previous owner stops playing and taking up server space. It's like changing the driver on the vehicle. As far as they're concerned they're not affected in any way. It's just faulty logic to justify getting a few extra dimes.
There's just one tiny flaw in this thinking: the original owner stopped playing. If they hadn't resold it, that would mean the company would have to deal with less server demand. Having stopped playing and resold it, the company has to deal with more server demand than if the person had stopped playing and
not resold it. The only exception is if the person resold it and
wouldn't have stopped playing if they hadn't resold it, which is a relatively rare occurrence (people don't generally resell games that they still want to keep playing). Thus resale of of the game hurts the attrition rate of server demand without compensation to the people hosting the servers at all.
