New submitter RicardoGCE writes "Apple has banned all iOS apps from carrying Saga #12, a comic book created by Brian K. Vaughan and Fiona Staples, and published by Image Comics. The reason for the ban is the depiction of oral sex appearing on the computer monitor that serves as the head of one of the characters. The content has been deemed pornographic, and sale of the comic has been blocked. Comixology will allow users to sync their purchases, however, so users of their app will be able to read the book on their i-devices. They just won't be able to buy it through the iOS version of the app."
Vaughan himself points out the sexual representation in this issue ("two postage stamp-sized images") are not as graphic or as prominent as other situations from past issues. The difference is that this depiction is of a homosexual encounter rather than a heterosexual one. Image Comics took the high road, saying they regret the decision, but that it's "Apple’s decision and it would be inappropriate for us to tell another company how to run its business."
Update: 04/10 18:36 GMT by S : As it turns out, reports of Apple censorship were wrong. Comixology posted today on their blog that they were the ones who decided to remove the issue of Saga from the app. They did so because they were trying to follow Apple's content guidelines. The issue will be available via their app soon.
