That's not why the financial stakes are high. They're high because ESPN has fixed price contracts into the future for the rights to broadcast sports events. If their subscriber base falls, they're still on the hook for those contracts.
The article "Is ESPN A Giant Bubble About To Burst?" [1] does a much better job of explaining the whole picture. It also gives a reasonable argument as to why subsidizing channels we don't watch benefits TV viewers as a whole. (I'm thinking about becoming a cord cutter myself, but the argument is still reasonable.)
