Directed towards Sam and Nebula:
To be fair, the Random House versus Apple debate got a lot of publicity this past winter/spring in the months leading up to the iPad release. RH is the only publisher out there of the "big 6" who remains off the iBook library shelves.
What is interesting, as I posted earlier, is that they HAVE reached agreements with many (if not all) of the other major eBook distribution clouds; Amazon via Kindle, B&N via the Nook and Borders via the Kobo.
Only the Apple relationship remains for them to establish. I don't think its a difference in philosophies as RH demonstrably is just hunky-dory about the Agency model. Apple isn't doing anything fundamentally different than Amazon in that respect.
What differences do remain is open to debate. I've seen commentary in the press discussing RH's views of Apple's long-term treatment of music and media publishers by forcing reductions in content pricing and obfuscation of reader demographic information (since Apple controls the transaction, they can hide who is buying what from publishers...something publishers really want to know and value highly).
Or it could be Apple "playing hardball" with RH and even though their content is freely available on competitive eReaders, they have told RH "You weren't with us initially...so FU now!" Who knows?
I used to work for B&N years ago at the corporate level (designed many of their superstores). I can tell you this much....unless things have changed dramatically, the profit margins on books sold at the retail level (hardback/paperback) are insane. Amazon, B&N and Borders sell a crapload of physical books. Apple is 100% digital. It is easy to 'squeeze the profit balloon' when you've got multiple channels and multiple products. Sort of like the car dealer who ups your trade in value but then also ups the purchase price of the new vehicle. In the end, you don't win anything but it looks better on paper. When you have one product (digital content) and one sale (digital content), there's no wiggle room. And given that Apple is a new market entrant for eBooks, it is also possible that RH had pre-established relationships with the other players to offer them price protection or "guaranteed most favored trading partner" status as well.
If I were going to play a game of chicken, I'd make sure I could protect my profits as long as possible. That could be one (of many) reasons RH isn't available from Apple, but readily available in every other major eBook format out there. Channel strategy is a huge factor when you are talking about players of this size.

Regardless, I stand by my original statements. Giving Apple the "good guy" status here is just as wrong as granting it to RH. There's big money at stake and if you follow the money, you'll find your answer. I'm sure there's plenty of blame to go around with both parties.
