You may think phone service stinks since deregulation, but don't mess with us, because we're all you've got. In fact, if we fold, you'll have no damn phones. AT&T - we're tired of taking your crap!

Our reading
An editorial interpretation.
The speaker admits customers may find phone service poor since deregulation, then turns the complaint into a warning: the company is the only option, and if it collapses there would be no phones at all. The closing jab says the firm is weary of being blamed. Defiant, bluntly self-serving pitch.
