His website publishes the quotes said by celebrities at one particular place so that they will be easily accessible to the users. It can be compared to the stock prices published by websites (of course, they have other news content along with the prices). All the websites publish the same prices, so that can't be duplicate content.

btw ..the difference between "he and they" is staring you in the face in your own final paragraph..
They probably are getting hit to some degree by panda for dupe content ( the "posted everywhere" stock prices )..but as their dupe content also has their own unique content around it ..they only drop a few places, and no doubt the movement in their "niche" is amongst themselves..and some of them will have become by now "trusted" and cited elsewhere as having thoughtful analysis of the figures they show etc or good articles or editorial content or comment..

He on the other hand will have only what he is scraping ..so he will rank lower than the people he scrapes from ..and unless he adds unique content to what he has scraped ( as long as other scrapers with the same content add even a little other unique content ) he will be below them in serps too..
