Apple denies Project Gutenberg app. because it “includes”

the Kama Sutra. It appears Wired broke the story about this inexplicable denial. The app, Eucalyptus, was created by Project Gutenberg and therein rest the "problem". The app does not come with any books, you search PG's database and download whatever you want to read.
Among PG's vast db of public domain books is the Kama Sutra, and Apple claims this work, first compiled in the second century CE contains "inappropriate sexual content" [N.B. I assume the PG version is the 1883 "Burton" edition and not the recent 2002 "scholarly translation"].
The interesting issue here is that Apple is precluding it NOT for something "in it", but something obtainable *through* it. Doesn't this mean that Google and all other "search-y" apps need to be blocked as they can "find" dirty text and pictures??? It appears that PG has coded a filter to protect iPhone users from the Kama Sutra and hopes to get the app least those who don't know how to use Google...or Safari. Oh, wait....hmmm. [Thnx to @ncacensorship]
