Nobody should be arguing that DTV would/is/will lose subscribers. Every pay service does. And DTV was starting to shed subscribers before the acquisition.
The question is whether T has helped stem that loss, or has exacerbated it. Numbers indicate that pre-acquisition DTV was losing subs at a rate lower than the overall industry compared to Dish, Comcast, Spectrum, etc. However, after the acquisition when T got to take full control DTV began to lose customers at a rate higher than the industry.
Secondly, after T bought DTV they had two video services, DTV and Uverse. T then rushed out DTV Now to try and keep cord cutters with a streaming service, but it was horrible, losing even more subs.
The next thing T did was basically ignore DTV problems completely. There were no efforts to try and keep customers at all. There was no DTV marketing, no attempt to try and make the packages more competitive, and no effort at all to try and merge DTV with Uverse to offer a single video source.
Then T poured millions into creating ATTTV, which was a third video service directly competing with DTV and Uverse, but one that depended entirely on fiber internet speeds to work. Fiber is very spotty and most markets do not have access to it, meaning ATTTV is a novelty service only available to a very few.
T's next step was to stop selling Uverse all together, and push DTV as an option only to rural customers, even though ATTTV is unavailable to folks in places like NY and LA.
Finally, T spent money into HBO Max, to compete with not only Netflix and Disney +, but also with HBO Go and HBO Now. Customers were confused, and the price of $15 per month is just too high, so the take is very low.
Now today, five years after T took over DTV they have lost almost 6 million subs since 2015, but they still have over 17 million DTV subs, meaning DTV is over 85% of T's total video service, with Uverse, ATTTV, and HBO Max single subs making up the remainder. Somewhere a lightbulb went off and T execs realize that DTV is still important, and is now returning to focus on it. Especially because the revenue T continues to get from DTV subs (measured by ARPU) is higher per customer than that from Uverse, ATTTV and HBO Max combined.
Of course, with this history, T execs refocusing on DTV probably means an even sharper decline in subs and a bigger loss of revenue.
Nobody is claiming DTV is perfect, or that if it was still independent it wouldn't be losing subs. But T's mismanagement has made that loss happen faster, and their Quixotic efforts at streaming and other video services boggle the mind by their pointless nature and ham handed execution.
If people here can't see that T ownership has made things worse for DTV, they must be blind T cult members
Five years ago T had the chance to do something really revolutionary with video. They had a subscriber base of nearly 25 million (combining DTV and Uverse), and if done right they could have launched a streaming service that might have been a Netflix k–ler. But it ended up being the punchline to the joke 'What happens when you put a phone company in charge of TV?'
