I completely agree with you. Apple should really be more "open" in protocols and interfaces they use. But, sadly, I don't think they care (as you say). They lose you and thousands like you (and in a few years might lose me too, but I'm not really fed up with it and have invested too much in Apps to be able to switch easily, and even if I could I wouldn't just now - I really enjoy my iDevices, despite all their vices), but this strategy "might" lure more naïve users into their platform. Which is what they want.

But, personally, I'd really love for them to use more "open" protocols. But, maybe it's not entirely their fault? ePub wasn't great for their dream of ibooks. It would literally take years to "standardize" the new file format through W3C or whoever is controlling ePub. So, they did the only thing they could: creating a new file format. Just like iMessage, FaceTime, iWork, iTunes, ... - I don't mind them doing it, just wish they would "open" their contrived file formats afterwards, so Linux guys could create decent iPhoto clones that we could "rsync" stuff between devices, etc.
