AT&T is not doing well. They never should have bought DirecTV. Instead, they should have turned U-verse into a OTT product like DirecTV Now, and invested the other $48 billion on expanding their fiber footprint. Some of AT&T's customers might be doing well, by bundling wireless, TV, and Internet, but the company is not killing it. All of that said, I am an AT&T wireless and Fiber Internet customer, and I am very happy, but I get the impression what I place value on differs significantly from many other customers. Hence the stream of people switching to OTT TV and T-Mobile wireless.
