SEO is snake oil. This is further proof that the whole "industry" is ruining the integrity and usefulness of the internet.
And if you want to place the blame where it belongs remember that Google is the company funding all this content scraping with their ads programs.
I just tried searching for a recent post from an official Google blog (about AdSense using referral data for more relevant ad targeting) and found a scraper site with their ads outranking them for their own content. Pretty sad.
Google gets paid for the scraped site because of ad impressions and possible clicks.
Google does not get paid for running an informative blog, in fact it's a cost to them.
Google cares about getting paid.
