I think they at least want the newspaper sites themselves to score the web hits. This means a payment back to AP, which is gotten from advertisers on the same pages that also pay for the hits. If somebody pastes a whole AP article into Huffington Post, none of that happens. Maybe if FR supported frames for such content so that the paper got its hit, they wouldn’t complain about FR any more.
So doesn’t Huffington Post have to play by the same rules we do, that is, post an excerpt and a link?
