Arguably if the source you're ganking content from is in the top 3 results, you might as well kill the scraped content box so that people can see more search results above the fold, since the content you scraped will be there anyway.
Of course, the boxes are good for Google, because they let them exert more control over visitors and traffic. Google puts enough of the source into the search results that the average visitor might never click through to Wikipedia.
Maybe google could give the potential ad revenue back to the sources.
(I don't think I've ever written a news article about a tweet and likely would not, barring extreme examples such as @WhiteHouse tweeting that the president had resigned or somesuch.)
