Scraping page titles and snippets to create a list of websites is one thing, but scraping unique content from the pages that keeps people on Google instead of going to the source site is a problem. Say a bunch of restaurants are given star ratings by Yelp. If Google adds those ratings to its search listings then users don't need to go to Yelp. Google gets a double benefit: Yelp's content enhances the Google brand, and it stops them going to external sites. Yelp suffers a double loss: It loses unique content and loses traffic. Google's Knowledge Graph is where Google scrapes facts that other sites have compiled, most notably from Wikipedia, and presents it as its own data. This devalues all the sites that have compiled the facts, but greatly enhances Google. When Google acts as a content site in its own right it inevitably comes into competition with the sites it ranks on the search engine, hence the (inevitable) anti-competitive behavior seen in the report.
