We all wish this. That it would come around and bite them.
Unfortunately, it doesn't appear that's ever going to happen. ESPN have been pursuing the identity politics angle for many years now, and...nothing. Yes, their ratings are down, but clearly not enough to make them change their minds.
Perhaps the owners are just too rich to worry about it. Once you get up to a certain level of wealth, money becomes unimportant, it's just one of several means to amass power. Power is the thing. Influence, control, leverage. Power.
So perhaps they may be getting less money from ad revenue because they're pissing off a lot of the "little people" like you and me, but still doing really well amassing power where they seek it.
The owners of ESPN, when they look at a map of the globe, maybe it has important terrain, terrain they'd like to control--like the eastern seaboard between DC and Boston, the west coast from LA to Seattle, the population band of eastern Canada, maybe an island here and there in Texas and Florida (Houston, Miami), and then their gaze shifts toward Europe and Asia. Maybe when you have this view of the world, what's happening in all those unimportant bits (like the other half of the US) just doesn't matter.
