As I have always understood it, you cannot select which channels are in your package. Even worse, the crummy channels that no one watches still make money from everyone who has the package. They are essentially subsidized by the popular channels.
I believe what you CAN DO, it continually petition and pester your provider to remove that crap from your package, e.g., you at least want a choice of a package WITHOUT fake news. If enough customers did that, or dropped the entire service, they might be removed.
Actually that is not how it works. All channels have a per sub cost. Complicated and confidential contracts build in discounts or even freebies for affiliated channels. The operator takes that into consideration to hold down his overall costs.
Even the big boys have to play by the programmer’s rules. Notice how every now and then they have to temporarily drop your favorite channel because of a dispute?
As a mom-and-pop cable operator, there was not much I could do but go along with the latest bad deal. Happiness occurred when I sold out to an aggregator several years ago. When the dinosaurs go out to play, the field mice scurry under rocks.
