I agree
without reservation that Apple is accountable for this. They choose their employees, they establish policies, they train them, they supervise them. I was only quibbling about the word "endorse."
More importantly, Apple extracts 30% of the sales of this garbage. It appears somewhere on an Apple web site. Even if Apple had a policy of allowing any app to appear on their store I would still hold them accountable for reselling this kind of thing and having it appear under their name on the App Store.
Their guidelines are not on a public server, however Gruber quoted the guidelines last month:

We will reject Apps for any content or behavior that we believe is over the line. What line, you ask? Well, as a Supreme Court Justice once said, “I’ll know it when I see it”. And we think that you will also know it when you cross it.
And:
Any app that is defamatory, offensive, mean-spirited, or likely to place the targeted individual or group in harms way will be rejected.
And if neither of those apply:
This is a living document, and new apps presenting new questions may result in new rules at any time. Perhaps your app will trigger this.
I think we're in violent agreement that this app has to go, and go swiftly.
