because Yahoo ceases to be a competitor in search.

Yahoo is going to use Bing technology for their sites. I think theres no question the DOJ will come to the conclusion that the deal is anticompetitive.The idea that the deal is anticompetitive may sound absurd to many who follow the search industry. Obviously Google is so far ahead of the game with regards to the search market, that there is doubt among some of us that Microsoft and Yahoo combined will even hurt Google significantly.
