That’s not even a fair analogy. If there was competition I would not have a problem with Comcast throttling a competing service. But because they are allowed a monopoly over entire regions, that requires some different rules.
I thought what we were talking about was much more narrowly focused, the case where a business structures their marketing to maximize the competitiveness of a service they already offer, rather than the much wider concern about whether effective competition exists in the ISP marketplace
Good luck pursuing some kind of United States v AT&T when there are multiple ISPs and not a monolithic target
