I haven't seen any Google-owned scraping or aggregating page in a result that I've clicked through.

What about Google Health results? Try [Whooping Cough] or similar. Top 'result' is a Google health page whose main column is all content republished from Medline. Right column is essentially 'more results' from News and Scholar.

It's not quite as bad as other paste-together pages of text and more results, but they're creeping in that direction.
