I think you can blame them though, and should. Florida has no problem sharing what they generate for the SEC with Vandy. Or Bama what they generate with Miss St. That's how a conference should work. If you don't treat everyone equally, the spurned are going to always keep their ear to the ground and loyalty is just lip service.
You're going to compare the big 12 to the SEC? Really? Vanderbilt is really the only program in that conference that isn't carrying their weight in football. Even when they are bad, the SEC schools have double the fans going to their games than Baylor, Iowa St, Kansas, K. State, etc, etc. The fanbases are larger, more rabid, and more loyal in the SEC than anywhere else.
the big 12 (like the big east) is top heavy, a couple national names, a couple average programs, and too many bad ones.
Which brings me back to my point. The Big East is sharing revenue equally are we not? Pitt and Cuse were being treated unfairly and that's why they left? They get basketball revenue, and football revenue. The basketball schools don't get football revenues. So who was being treated unequally or unfairly, and why is that the fault of the hybrid system?
I don't like the hybrid system, but it's not the reason the big east fell apart. If we dumped the basketball schools a few years ago, Pitt and Cuse still go to the ACC if offered. More money, more stability, period.
