WB pitched that to make it easier for them to be acquired by shunting all the debt to the channels entity - but it was unlikely the debt owners were ever going to go for that as presented, there would have been quite a significant chance of the channels group going under and them losing all the money.
But ultimately it turned out that enough entities were willing to bid now, before that split, that there was no point continuing to work out how to do it. Netflix will, presuming this deal completes, be the owner of CNN/TNT/Discovery at al.
Now, I am very sure they will look to sell several parts of those off - there is absolutely no way Netflix leadership wants to continue to own TNT - but that will have to come later.
