@drawingdog @aires Well, no -- what they’re selling is higher-quality results and privacy, and they very much have their own algorithms on top of all of those sources. It's not just building a dumb stack of everybody else's results.
Yes, it's probably possible to boil that all down yourself, but to a large degree that's just saying you don't want a search engine at all. I think relatively few people want to go to that level of work.
