I wonder if the broadcasters could let the content providers break the contract, in exchange for some agreement. Or if they can sub-license the rights back to Netflix, and profit as a middleman.
It would need to be a profitable arrangement for all involved; these are publicly listed companies and they're legally required to act in the best interest of their shareholders.
With a three way split on profits (middleman situation) it's unlikely that it would be possible for all three organizations to get the best deal for their shareholders: someone is going to be paying more or selling for less than they ideally would like to.
In order to sell the rights the seller would have sell them at greater than the profit forecasted to be returned by their ownership of those rights which would be unlikely to provide any value to the purchaser, meaning that they wouldn't be acting in the best interest of their shareholders.
Both of these would also need to be expressly permitted by the content provider as well, adding another layer of legal expenses.
