I've lived in several cities across different regions in the US over the last few years, and I've always had multiple options for ISPs. Granted, more rural areas will suffer from this just as they do with cell service. But most large population centers have several options (I believe there are 3 in my current area).
This whole doomsday view of the repeal is such an overblown rhetoric. Free market competition will force service providers to maintain fair packages and pricing, just like with cell services. Even 5 years ago, there were really only three cellular options that were worth using (ATT, Sprint, Verizon) and they were still expensive and capped data. Now you've got a dozen options which have forced the big providers to offer bundles and lower prices while also offering uncapped data.
Obviously, cellular and internet service providers aren't going to operate the exact same way - but forced transparency on cellular providers yielded positive results for consumers. The FTC will do the same with ISPs, forcing transparency on all services.
There are also a lot of assumptions that ISPs will block access to certain apps and services, such as Netflix or Hulu, while only providing there "preferred" option (ie: block Netflix and only allow Hulu). I don't see this being the case. Again, looking at recent changes to cellular providers: T-Mobile now offers free data access to Netflix while still having users spend data for other services like Hulu. If anything, we will see competition among ISPs providing bonuses to consumers as opposed to punishing them with certain applications.
I could be wrong, and I'm obviously drawing conclusions from another similar sector. But I do think the anti-repeal rhetoric is more of a political ploy and media frenzy than it is realistic. We will see.
