Let me sum it up, for those who don't like the choppyness of the patched together video.
Shoo recently submitted a title to iBooks, only it's not live yet in the iBookstore. By the time he made this video, Shoo had been waiting over a week for Apple's censor to get off their duff and approve it. For obvious reasons, that should have happened in hours, not days.
A technical review for iOS safety standards could have been done in under a few minutes. It doesn't take that long to do a virus scan, confirm that the file meets the iBook spec, and make sure that it doesn't contain malware.
The only reason that it might take a week is that Apple is making sure that the content meets with their approval. And that, my dear, is censorship. Pretty heavy handed censorship, too.
It's also not the first time that has been picky about approving content.You probably recall that back in February Apple bounced a title from iBooks because the author had included links to Amazon. That is a relatively minor case compared to the one I found last year. Apple was pushing developers to release their apps as Epub, not apps, even though some wouldn't work well as Epub (this was pre iBooks Author).
In the long run this is going to bite Apple in the ass. I would expect more and more authors to follow Shoo. He's gotten fed up with the delay, so his next work will be made for the Kindle Fire and submitted to the Kindle Store.
Amazon doesn't have nearly the same obsession with controlling what gets into the Kindle Store that Apple clearly has with iBooks. Of course, they might pull it later based on their own capricious decisions, but at least it gets in.
