The answer is (drum-roll): Randall Stephenson!
T's CEO Randall Stephenson is an unmitigated disaster. He should have been fired after the T-Mobile fiasco years ago. My regret is I did not sell then. I'm all out of T now. Good luck to my friends still holding on.
Yes indeed, Randall Stephenson is the one mostly responsible for T's lamentable condition. I'm out today - all 19,000 common shares of them.
