Everyone seems to realize the petition itself isn't worth the imaginary paper it's printed on. Even if you get a response, it could be as simple as, "That's nice. You're wrong. The decision stands."
As TheSpoom stated above, there's no reason you can't have a binding contract to make sure the carrier doesn't lose money subsidizing the phone (in fact, you're probably under one of these contracts now) completely unrelated to a carrier lock on the phone. As long as you're in a legally binding contract to pay them the money, they shouldn't really care if you can use your phone on another network. If you want to keep paying AT&T $80/month for the subsidized phone and also pay T-Mobile another $50/month for service on the same phone, why should AT&T care? They're still getting their money that you agreed to pay.
On the other hand, due to the dismal state of cell phone technology in the US, most people don't really need an unlocked phone. The major carriers are on completely different technologies and bands - a Verizon CDMA phone simply won't work on AT&T's GSM network (and they use different LTE bands too). T-Mobile is also GSM, but they use different bands, so (currently) you won't get 4G and maybe even 3G depending on the phone's hardware. Hooray for buying a brand new $700 iPhone 5 to get 2G data speeds on it. Even if you could make a satisfactory switch from one carrier to another, would you want to keep paying AT&T the $80 monthly fee (or the large ETF) under your contract while also paying T-Mobile $50/month for the actual service? In the not-so-extensive looking I've done, there doesn't really seem to be much discount for having a non-subsidized phone anyway; if you're going to be paying the same $X per month, you might as well have the carrier throw in a subsidized phone. Most people are going to keep the phone and service they have for the full duration of the contract, making unlocking completely irrelevant.
Granted, there are some exceptions (relocating unexpectedly, international travel, etc.). I'm used to the iPhone world (it's supplied by my employer), so maybe Androids are very different. But from what I've seen, it's a non-issue for most people in the US. Verizon will unlock the GSM portion of an iPhone for international use (it didn't work for me on AT&T's domestic network, but I didn't end up using it internationally, so the unlock might not have actually been in effect yet) and AT&T unlocked my old off-contract iPhone by simply filling out a web form. In my experience, the carriers seem fairly willing to allow you to do things if it's actually for a legitimate use, as opposed to you simply wanting your phone completely unlocked for no good reason.
Ideally, I'd like to see service and hardware priced separately, with or without contracts. Plan A is $80/month with your own phone, $75 if you agree to a X-month contract (think of it as a bulk discount since the carrier knows you won't ). If you want a new $600 SuperPhone with your Plan A, it costs you $150 plus an extra $20/month with a 2-year contract. You end up paying a little more for the phone ($630 total), but you don't have to drop $600 right now on something you're used to getting for free. If you want to cancel the contract early, you're responsible for whatever the remainder of the amount owed is. If you have your own phone that you already bought with your own money, you know that you're saving $20/month on it. The carriers don't need locks because you're signing a contract to pay them enough to cover the cost of whatever you're getting, regardless of whether or not you get service through some other carrier. And to make those unlocked phones actually useful, let's see the carriers standardize (along with the rest of the world) on a network, so you can use your (paid-for) phone with the service of your choice.
This could result in some price increases if the carriers know that whatever contract they come up with for subsidizing the phone (monthly cost + ETF) needs to cover their actual cost, since they're not necessarily roping you into two years of overpriced service as well. I've seen a few deals where it's actually cheaper to sign up for a contract and pay the ETF than to just buy the no-contract option, so they'd need to make sure they closed all those loopholes. On the flip side, if they know the hardware contract is guaranteed to cover their costs on the phone, they should be able to lower the service price some since they're not including the hardware-subsidy compensation. It removes some of the black-box mystery from their pricing schemes (it's currently just a monthly phone bill, so most people don't realize the costs associated with each component), so I doubt the carriers would actually go for this.
