My dude, because you weren't aware ESPN is owned by Disney, I'm going to assume you don't know some basic things. Not trying to be offensive just explaining why I'm typing out commonly known knowledge.
ESPN needs to find a way to retain customers and a way to charge more for ads. They have lost viewers and revenue per subscriber every quarter for a consistent amount of time. As such, IF Disney was inclined to get involved in this dispute they would need a team that would create interesting matchups that they can sell to their advertisers--NOT a team that they can rally the home crowd around.
Additionally, ESPN itself will make the same amount of money on the school itself whether UCF is in the SEC and ACC. It would make more fiscal sense for Disney to say Miami to SEC and UCF to ACC.
With all that said, Disney makes more money from Disney stuff than it does from ESPN. At this point, ESPN is the equivalent of a property that keeps making less and less money but which you can't unload because everyone knows it isn't what it once was.
So I hope with that, you can take a deep breath and realize someone is absolutely taking advantage of you and probably still laughing that you believed them.
