It has plenty to do with the broadband market, if you happen to be an AT&T subscriber, and especially if they're your only choice. This, coupled with their no longer being restrained from the kinds of shenanigans that NN barred, positions them to force preferential choices on their subscribers and wring more money out of them for the privilege of accessing competing services.
This is only good for people holding T and TWX, and probably not even most of them.
I would certainly agree with that but your original comment was specifically about competition in the broadband market, which this deal has absolutely zero effect on and your post seemed to be based on the common misunderstanding of TWC still being part of TW.
That's one of my complaints when courts pretend to rule in favor of stock holders rights. In practice there is an inherent conflict of interest between management and the stockholders whose interests are diverse and barely represented.
