As a courtesy to relatives, who by virtue of not being locked should be presumed innocent, providing some more convenient ways to check up on their loved ones might be a nice touch. You could time box it, restrict it to certain hours, etc. But there's no need for extorting people over this.
Since the US tends to run a lot of its prisons as businesses, it's not surprising that the contractors involved are ripping off their customer (the state).
John Oliver recently did a nice episode on the abysmal state of healthcare in prisons vs. the insane profits that contractors are making. I imagine this is the same for this kind of stuff. Expensive, inefficient, stupid at many levels, and enriching some really dodgy companies and people in the process.
