I think he'll prevail, too. I hope he does.
But, still you sign a contract...you should take the time to check if your prospective new domicile has LOS.
If not, either try a different location, or be prepared to be a big-boy and pay the ETF, that you willingly agreed to as part of your D* service.
You can move anywhere, whenever you want. Just be ready to actually live up to the obligations you voluntarily sign-up for, too. With freedom of choice, comes personal responsibility.
I don't know about the OP, but I have never SIGNED a contract when they extend my service agreements. I have verbally agreed, but never signed anything.
You are making it sound like this guy abandoned a mortgage or something. With freedom of choice comes personal responsibility? Are you joking? This is TV we are talking about.
Bottomline: He moved WITHIN their listed service area. He told them he was moving, DirecTV sends installers, and they cannot provide a signal. They can no longer provide service to him. He didn't end the service contract, DirecTV did.
