I know it is your "natural" interpretation, but it does not automatically make you correct. In this case, I did not give anything particular stance of if prisoner should be given free calls or not. I merely state that being a good thing for somebody is really not an supporting cause why it should be free. There might other valid reasons to provide it free or not free, but being a good thing for prisoner is just a poor argument. The same goes for things like since non-prisoner are already paying bunch of things for the prisoners they should not be bothered to pay another thing.
