I wonder how they will treat this change. Because including the feature then changing it to pay is a change of the contract terms that might let people out of contracts...
Either way a free tether solution should be possible.
This is a little ridiculous that more people aren't using common sense with this. You can't get out of your contract this way, and why not? You're clearly being told that you are being GIVEN this feature for FREE until 05/15/2011. Don't bother writing that date down, because the contract you sign probably mentions this promtion, then you'll probably get a flyer, an email and and ad show up in My Verizon clearly stating "4G Mobile Hotspot FREE on Thunderbolt Until 05/15/2011". You might even get a letter in the mail welcoming you to this free trial. Then likely at least 2 reminders as the free trial is about to end, likely mail and email. You might even get a text message on your phone. Then, on 05/15/2011, it's probably going to stop working and you will probably be told the new rate of 2 GB/$20 for the feature (and no obligation to keep it) and you'll be asked if you want to add it.
So if you decide to ignore this clear forum post that has told you, all the news articles and then Verizon's very thorough warnings about the feature change, then no...you don't get out of your contract with no termination fee. You get a medal for being cheap. You were clearly told this multiple times and it's nobody's responsibility but your own.
