Verizon can kiss my @$$. I OWN my device, so I can legally modify it in any way I want. I also pay for UNLIMITED DATA, so I should be able to use that data however I want, because I paid for it. There is no little rule that says I can't use more than so many megabytes per hour. I pay them for the SERVICE, I think they should just back off.
No, you pay for "Feature Phones, 3G & 4G Smartphones" Unlimited Data. They are selling you a service priced upon the average usage for a person using one of the devices in the plan description. Smartphones in general use less data/network utilization because they stream lower bitrate video, music, many larger sites today recognize the device from the HTTP request and serve the mobile site. I travel extensively and use my DX tons, I have never come close to using the amount of data from the phone in a month that I do in a couple weeks when I have to tether for work (yes I pay the $20 when I know I'm going to need the service).
I can't argue that Verizon charges a premium for their services but you have other choices, just because they charge more than other carriers for smartphone data doesn't you're paying for a different service.
This whole "OMG I'M ENTITLED" is a BS rationalization. I don't give a crap that some call it "stealing," what annoys me is the a) obvious self inflicted delusion that people want to believe that unlimited data for a phone means unlimited data for whatever they want, b) that it's giving Verizon additional rationalizations for limiting our abilities to mod our phones (the "OMG see they're "stealing services" we can't let them root).
If you're going to lie to yourself that you're entitled to tether do the community a favor and keep it to yourself.
Edit: Although I do agree that you own your device and should be allowed to do whatever you want to it and I think it's a reasonable request as long as we don't cost the carriers additional money to support us (in other words, hardware warranty should remain intact but don't expect them to support the comprehensive warranty if you're modded).
