Google has been acquitted of the anti-competitive allegations brought to it more than two years ago by South Korean search operators NHN and Daum Communications, the Yonhap News reported today. Back in April 2011, the two firms accused the Mountain View company of having an unfair advantage by making its own search engine the default on the Android operating system. After a couple of raids and a lengthy review process, the local Fair Trade Commission has finally decided that Google didn't hurt NHN or Daum's competitive chances at all. FTC officials said that both companies presently enjoy a healthy chunk of the domestic search engine market -- NHN's portal maintains a good 70 percent share, for example -- and that users could easily download NHN and Daum apps onto their phones as alternatives. Chalk this one up as at least one victory in the search giant's seemingly never-ending battle with authorities.
