I'm never sure if Fox is serious with its luddite take on the Internet. Milwaukee's Fox 6 airs The Simpsons and other shows right on time and for free, but you want to see the same content on Hulu, you have to wait a week. Unless you pony up for a subscription. According to the Verge, Fox is pushing Hulu now to authenticate against cable subscriptions to lock down the service even further.
Oddly enough, there doesn't seem to be a clear plan for Hulu Plus in this plan. I searched through the New York Post article The Verge linked to, and it isn't detailed there either. There is at least an implication here that Hulu's business model isn't even a consideration in this plan, and this is just another attempt to keep people paying for cable plans.
It isn't clear when this impasse will break. Cable customers are shrinking over time, and many of those cord cutters are using Hulu and other video services to replace what they got on cable. That upsets cable companies who are big contents biggest customers. Until Hulu, Netflix, Apple, and Amazon can actually outweigh Time Warner, Cablevision, and Comcast you can't expect to see them play nice even if they do own Hulu.
