One difference in this story is.... Google was vertically integrated from the start: They sent out their own bots to scan the internet, they had their own reverse index, and created their own algorithm. I'm not sure about DDGs backend---but if people use the g! tag, its almost as if DDG is simple chrome for Google. Maybe that'll be the future: Google will become the maker of engines, and let everyone else make the car.

As far as I know, DDG uses both data from other search engines (Google, Bing) as well as its own crawling bots. If they only used their own crawlers, with the current size of the internet it would take a long time for them to get a good amount of data.
