I get the ruling, but then again I don't. Regardless of apple, or anyone else, if each publisher was offered the same deal, and accepted it, how is that price fixing? Apple encouraging publishers to keep their prices competitive while still making them more money doesn't really sound illegal. Considering the # of calls and meetings between publishers, it seems like Apple set the terms, proposed them individually to the companies, and they accepted it.
App store developers are offered the exact same deal of apple taking 30%, of course they can set their own price.
Regardless of if it was Apple or Google, or Enron, this doesn't sound illegal to me, a layperson, who understands that writers/publishers need to make money to some extent.
Because you're looking at it logically, and not with the "I'm entitled to (insert need here)" mentality that unfortunately is pervasive in this country....
