unlock the bootloader of galaxy s4 i337 (why it Locked)

We the people, want to unlock the full potential of our phone. We want full control of the Bootloader, Kernel, and Rom... There's no reason to lock the bootloader, let us do what we will with the phone and train your staff to look for OS corruption to prevent people from returning the phones... When i paid full retail for my car the Ford dealer i got it from did NOT tell me what i could and couldn't do with it nor did they try to prevent it in any way. So why is it when i pay the FULL $700 for this phone OFF contract ATT can dictate what can and can not be done with this device. I am not even an ATT customer... It is my device, I should be able to do what I please with it... As a software developer I'm used to being able to do what I'd like with my hardware. This flies in the face of innovation that a phone like this is capable of. Please stop crippling innovation and Unlock the Boot loader!... I have paid the full price for my device and I have the right to full access. Please unlock our bootloader... I don't buy a Dell computer only to have them say I can't reinstall or modify Windows on the phone, so why is it ok for phones?
