I still think that's anti-competitive douchebaggery. iTunes has become the standard platform for organizing music, thanks to the success of the iPod. I think it has elevated to a position where Apple should have to tread carefully in anti-competitive waters.
All the information in your iTunes library, including playlists and such, is stored in an open XML file in your home directory. While I think it's a mistake for Apple to play cat-and-mouse with Palm over this, it's not as if Palm couldn't write their own syncing background app that does the exact same thing.
How is that anti-competitive? Apple has done absolutely nothing to prevent Palm from creating a a competing product to either iTunes or the iPod/iPhone. They have in fact given Palm a very strong incentive to do so instead of parasitically hijacking Apple's software.
I'm a huge Apple fan, and I'm extremely sorry to see them turning out to act more like douchebags each day.
