David Wineman:

Apple is trying to establish a rule that whatever I create with this application, if I sell it, I have to give them a cut. And iBooks Author is free, so this arrangement sounds pretty reasonable.

Watts Martin responds:

So Apple’s “audacity” is that they’ve created a snazzy creation tool that, from all appearances, only works with their viewers. Wineman is correct in that it’s the license, not the technology, that prevents you from taking a .ibooks file and selling it somewhere other than Apple’s store. But you don’t have much reason to sell something this thing creates outside Apple’s store, ’cause it ain’t gonna be creating those snazzy multimedia books for your Kindle Fire.
