Theft of Service. Learn it, love it, live it. Are you getting a premium service without paying for it? If you get basic cable and buy a box that gets you premium channels that's also stealing, this is no different. Yes, I think cable is way too expensive and I think I should be able to get everything for $60/month. How do I rectify that? By disconnecting my cable and realizing that I CAN get everything for $10/month via NetFlix if I'm willing to be patient.
3. The buffet examples are close, but it's not bringing friends along with you it's packing a Hefty bag and loading up to take food home with you. It's all-you-can-eat, but only for one sitting just like it's unlimited data only for one device.
4. Whether or not YOU think it's illegal or immoral is irrelevant unless you can afford better lawyers than Verizon. I personally think it's immoral that the Porsche dealer just leaves those cars parked out front, but it doesn't mean I can take an extended test drive to work every so often.
A note to people who tether without paying - you're the reason Verizon will continue to pressure manufacturers to make it harder and harder to root their devices. Don't complain that this bootloader is locked or that rooting method no longer works.
A note to Verizon - entitled consumers will always try to steal tethering services and the odds that you can actually stop them are fairly small. Please consider going to $40 or even $50 a month across the board for data services and giving away tethering for free. It's also probably a much smaller PR hit than billing or prosecuting people who tether (especially those dumb enough to admit it in a public forum)... Of course, just detecting it and sending them a nasty note asking them to stop or you'll add the service to their account will also go a long way.
