This is just another negotiating tactic by NBC. They did this before with iTunes and they're doing it now with mobile video. It isn't just Apple. Hulu is blocked on mobile devices last time I checked (even if they have flash installed). The execs are trying get a better bargaining position with Apple so they can then use any gain from Apple to justify changes elsewhere (such as charging for Hulu...ever notice how the ABC app is free and was released at launch). They're pretending this is an Apple only thing so people don't catch on to what they're doing.
