The problem is the combination of this evil clause and Apple's general attitude and evilness. First on the EULA: even if you used a program to do a formatting, said formatting is still your work, and the EULA recognize that by using the term work, so Apple is basically saying: if you use our "free" tool you have to give us a part of your work. So how exactly is that free? i don't know. Then what happens if you use something else to do the formatting then just convert using Apple program (if that is possible)? Or if you can't convert redo exactly the same formatting, or something really near. Apple risk to argue that you breached the agreement even if you technically might not have. And then what happens if they recognize that you used another tool to publish on other platform, but the too version are still too close to their taste? That's when Apple's general attitude and evilness will enter the game. They will say: I don't publish you, and I don't have to give any reason for that. You might say, yeah it is the game, it is their right. Except two things: the kind of people who object that typically also fake a taste for liberalism and free markets and so on (they are more probably thinking about something anarcho-capitalism style and how it could be great to make a lot of money fucking people all around you just because you can). I recognize that given the current laws, it is not obvious that Apple's don't have the right to do that, they even might have. But I found this way of doing business highly disgusting. The second thing is that a numerical publisher in Apple style has nothing in common with a real publisher. Their marginal cost for publishing you is absurdly low, their margins guaranteed, and they don't help you with you work (well yeah they kind of help you by "giving" you a program, ok in that case i suppose buying a fancy pen gives the builder some right on the story you wrote with? -- in any case this "help" as nothing in common with the help of a real publisher). It all can be summarized with: Apple is constructing a giant monopolistic market, because well it is obvious that monopolies works and brings an absurd amount of money. And now every other giant multinationals find how brilliant this is and are trying to do the same, even for PC. They might even say it is not monopolies because they are multiple of those, and if they turn their sentence to say that "well" people might even believe them. If this is the kind of world you want and like to live in, good for you. On my side, it makes me vomit.
