What if every web master, blogger, and writer got together to flood the internet with trillions of pages of duplicated content(s) daily. If Google de-indexed all of it then the world could sue them for cencorship, race based crimes, religious crimes (you know, postings and articles written about, by, or for race and religious issues). Or at the very least people might stop using them and switch to Bing.
Then we get the top guys here at the Sun to produce a new competing search engine. Immediately, we will gain control over 62% of all internet search. We will call it "Sunsearch -Search all information under the Sun"
Then we will remove the crap content we manufactured and offer to sell the new search engine back to Google for...
...100 Billion Dollars!!!!!
