The new iBook licensing agreement means that content that you create in the software is de facto owned by Apple because you cannot sell it anywhere except through Apple marketing outlets. And if they reject it, you cannot sell it to anybody else, either. In other words, if you create in the software, you become a sort of indentured servant to Apple. It’s as if Microsoft said that content created in Word was owned by them and could only be distrubuted through outlets they controlled. It is EXACTLY the same thing and mark my words, the entire software industry will sieze on this.
