If you have broadband from Sky, you are knowingly using a content company for your Internet provider, rather than a company that actually makes its money on providing Internet access. You don't have to do that here, unlike the US. It's very much your own fault for using such a service.
I agree that that seems like a bad choice, or at a minimum, one is choosing to do business with a company that has to internally negotiate an apparent conflict of interest. (Or, vertical integration if one has a generous take on the situation.) I am not so familiar with the layout of ISPs in the UK, but if other choices than Sky are present in a given locale, then, yes, the choice (I would make) is clear.
However, how does the Sky situation differ from the Comcast (content delivery) / NBCUniversal (content production) relationship? Verizon, AT&T, and TWC, as far as I can tell, are only content delivery services. I don't have specific statistics on hand, but I assume that for some people in the United States, Comcast is (unfortunately) the only viable broadband service provider.
What are you smoking, and will you share? Most people in the US can chose from one or two of the handful of large ISPs - Comcast, TWC, AT&T, and Verizon. The Lucky ones can choose between two or three of them, many only have one real option.
All four of those ISPs are content providers - hell, you the Triple-Play is a thing precisely because they all sell subscription TV services as well as internet and voice...
