Food Fight: the Corus-Rogers brand battle explained

The licensing of American specialty brands in Canada went all WWE in June as Rogers swooped in and wrestled away rights to The Food Network and HGTV brands, among others, from Corus. The new deals with Warners Bros. Discovery takes effect in January. There are indications Bell Media can't count on re-upping some of their Discovery brand imports either.
What has sparked all the brand swapping? What are the ramifications for Corus and others? Daniel Eves, who for years was at the table negotiating licensing deals with American Studios while SVP at Corus, says the potential for all these specialty swaps has been there for several years. He explains it all as this week's timely guest at brioux.tv: the podcast.
