In a move that should have shocked no one, Apple updated their iBooks Author EULA. The new EULA clearly confirms what calm and patient folks said from the beginning: Apple isn’t interested in restricting your ability to distribute your content. They only want a piece of what is built specifically with iBA:
this restriction will not apply to the content of the work when distributed in a form that does not include files in the .ibooks format generated using iBooks Author. You retain all your rights in the content of your works, and you may distribute such content by any means when it does not include files in the .ibooks format generated by iBooks Author.
Don’t worry, though. I’m sure there’s still something scary hiding under your bed.
