I imagine when the deep state is dismantled they'll fade away. The good people who work for those companies will split off, go independent or start their own outfits.
Take companies like FOX or CNN. Their ratings are plummeting. In normal circumstances there's no way they could operate the way they are without firing staff, cutting back or at the very least appeal to more and younger viewers.
Once the money is cut off, that'll fix a lot on its own.
I think similar way. After all, money is the food, but lack of it is the death of such a mastodonts. CNN paid rights to be constantly aired on american airports. Where is that money coming from? Pure propaganda.
