Not that surprising considering AT&T is so far underwater they're in danger of seriously disturbing Cthulhu's nap time.
That HBO Max figure is potentially a bit problematic though. Right now I believe the US chunk of that 60 million is around 44 million subs across both HBO Max and HBO domestic. But a sizeable number of AT&T plans include a sub as part of the service. Presumably if the entertainment side is sold off there's not a lot of point for AT&T to continue subsidising that service, especially with the lack of competition in the US mobile market. How many people actually pay to subscribe directly to the service is, as far as I'm aware, not readily available information...
As for the rest... I'd like to say it can't get any worse than AT&T's leadership but recent history is littered with evidence to the contrary. Still feels very weird that a group with rights to DC comics, Harry Potter, Looney Tunes, Lord of the Rings (at least on film), the Lego movies and the Monsterverse ends up needing to be spun off for a quick buck in the current geeky pop culture world.
