That's what I meant by, we can debate the merits of the History channel to begin with. I only took challenge to the notion that there is a world in which unbundling happens and consumers get to watch the same content for less money.
Whether or not it is "mis-serving customers" depends a bit on whether there's abuse of monopoly power, which is an argument one can make about the cable companies, but not so much about the over-the-top services like HBO Go, Disney+, Netflix, or Prime, all of which are structured as a bundle. I'm not sure Prime customers, for example, are unhappy or feel mis-served by being able to watch TV shows on top of being able to order items with fast, free shipping. Bundling can be used for nefarious value-extraction in a monopolistic market, but it can also bring consumers value, so we shouldn't conflate the two.
In many competitive markets, bundling is often a consumer's preference that does serve customers well. For example, most coffee shops don't charge for sugar, creamer, and other condiments, and you maybe have some aggrieved consumers complaining that they should get a discount for drinking only black coffee. It's likely that coffee creamer companies would go bankrupt if people had to pay for condiments at every coffee shop, and we can debate whether it's even a good idea then. But on the whole, I don't think that turns into an argument that coffee shops are mis-serving customers by providing condiments that are free of charge, that is to say, bundled with the price of coffee.
Personally I live in an almost perfectly unbundled world of content already, because I tend to buy or rent the TV shows that I'm personally interested in. This works for me because I have little time to watch, don't like ads, and have enough disposable income that I'm not thinking twice about cost, but I'm not sure that many other consumers would be satisfied with the kind of entertainment experience where they have to pay $2 per episode of their favorite show.
