Does it have to be a search based interface to the indexed data?
Does finding a link to the scrapee have to be the primary purpose of the site (and therefore google would be constantly getting "worse" by this scale)?
So how prominent does the link back have to be for it to be ok?
What about the summarized data from there that search engines are adding these days, so you don't need to leave the google results page to get your answer but the data still comes from some site that you rarely notice the name of?
edit: as to your curiosity, I honestly do not see the line that you see. Unless it's that the link back to the source is required. I don't know that I agree with that but I would understand it, although that gets harder and harder the more you massage your dataset to be useful to users.
