No no, I think it brings up an excellent point. (Okay maybe he does have an axe to grind, but does that excuse what's actually going on?)
In a recent meandering about the nuances about cell phone plans, in an attempt to find the best one for the lowest cost, I came across fine print details about tethering. Pretty much all prepaid services (Net10, Straight Talk, Aio, iWireless, etc.) forbid tethering your cell phone to any other device. Which is... Well absurd when you think about it.
But it's somehow legal.
Should an ISP be permitted to tell you how you're allowed to connect to their network, explicitly prohibiting setting up a wireless network? It's tantamount to having a toll road forbid anyone from using their road because they passed over a bridge a few miles back (and they don't want any bridge crosser coming through their road).
There's a practical reason for it, sure (tethering increases data use which means greater cost), but as I said before, this illustrates a greater point. And that's that we like to find excuses to find ways around rules to partake in exploitative behavior. The question of it being right or wrong never even entered into their minds; instead it's, "Can I get way with doing this?"
Hobbes would have a field day with this.
