More importantly, the people asking for a "censorship-free search engine" are expressing an incoherent desire. The whole point of a search engine is to take the zillions of web pages that have matching keywords, push the crap to the bottom, and leave the gold on top. A system that does this is inherently censorious. We're just quibbling over what the criteria should be.
What our world lacks is a reasonably-quick way to hold Google accountable when they fail to represent the interests of the public who searches with them. The real-world consenquences of their filtering decisions need to filter back to the people making these decisions. Because "just don't make any filtering decisions" isn't going to result in a usable information retrieval system.
