Correct, BTN isn't going away yet. I think they have a few years left on that deal. But you're ignorant to reality if you think the end game of the media companies isn't "direct to consumer." They understand that live sports is the only content people will pay a premium for. Think of the channels when you were a kid pre-cable.
ABC - owned by Disney, which also owns ESPN, pushing content onto D+, Hulu and ESPN+.
Fox - all non-sports assets sold to Disney.
CBS - owned by Paramount, pushing content onto Paramount Plus.
NBC - owned by Comcast, pushing content onto Peacock.
The dream of these companies is to sell everyone a content bundle at premium prices where they get to keep the money rather than dickering with cable companies over carriage rates every year. Everyone wants to lock up their own ecosystem and Comcast/NBC sees the writing on the wall, if ESPN locks up the Big Ten and has the ACC and SEC plus the tier 1 Pac 10 games, they will be able to launch a college football specific app and charge $100 or more a year for it and it will be a better deal for customers than even getting cable for 3-4 months and it will create a monstrous revenue stream for Disney. Disney knows ESPN is in huge trouble. It has made money for decades off the "ESPN tax" on cable subscribers and that is dying very quickly, so they need to hammer the price inelastic purchasers. And they will.
