No, the way to handle this is for Disney to declare Nexstar, Tegna, Sinclair in breach of contract, and turn off their network affiliation instantly, across the board. Disable their satellite downlink converters. No GMA, no ABC news, no Bachelor/Bachelorette, no Abbot Elementary, no any ABC Primetime, no ABC/ESPN sports, no newscast actualities, zilch. Leave them 100% in the lurch.
Which outfit do you think has more resources to ride out this kind of hit? Disney? Or Nexstar, Tegna or Sinclair? Anybody think it's not Disney? The station owners all of a sudden lose a ton of their weekly programming and have to hustle to get replacement programs on the air. Disney still has a big chunk of their affiliates, and if they offer the network shows temporarily to displaced viewers in the other affected markets via streaming, they'll come off as the good guys. In the meantime, ABC can shop the affiliations around to independent stations in those same markets, and they'll probably find wiling takers, while Nexstar/Tegna/Sinclair all become instantly-less-valuable indies to advertisers and Wall Street.
And one more thing to keep in mind: Nexstar and Sinclair both need financing to complete their acquisitions, and all the financial assumptions are predicated on current network-affiliates market value, assets, liabilities and cash flow, which would take an instant hit. And Tegna needs to be acquired, and is banking on that deal completing.
Chairman Carr can't dictate what Wall Street does with its money. You've got to fight fire with fire.
