Yes I was with Verizon for many years and had true unlimited and was grandfathered in up until 4 years ago when I left them. Like you, I couldn't see the big deal about tethering because the way I see it I am Not stealing data but simply transferring it to a larger screen. I live out in the country and tethering or satellite is my only option. On this same forum some thought I was "cheating" and I caught a lotta flax. It does state no tethering in the agreement and I assume it is to charge another fee for Hotspot. I do know many have been busted through the years and hear now they can't prosecute, but I don't know that for sure.
