I've been reading over this thread for a few minutes, and I feel the point I agree with most begs to be reiterated.
I have my unlimited data plan grandfathered to me by Verizon for my iPhone 4. I play by the rules and don't jailbreak it (mainly because of my dev iOS 5), and therefore I don't try to cheat Verizon. Granted, I did do that when I had my HTC Incredible I rooted, but back then I didn't understand that I could potentially be punished by my carrier for such an action.
Again, it's been said in here, but you agreed to this service. Chances are, if you don't like it, pulling out now and paying the ETF will benefit you more in the long run if you truly think you've been wronged. At the end of the day, Verizon is trying to make a profit, which isn't such an evil thing. The market closed the other day, and APPL was the most profitable stock on the market. I don't see you fanboys yelling and calling Apple evil.
I think it's safe to wager that the people who jailbreak their phones and tether for free are an extremely small minority, and in the sense of running a business, you're not the kind of minority whose best wishes need to be taken into account. You are doing something that Apple has rather quietly taken a stance against, and doing something that breaks your service contract, respectively. You can't expect fair treatment.
I'm all for freedom of the things you pay for. However, if you break the rules you live with the consequences. Don't do the crime if you can't do the time, if you will.
