You could split Google in Search/Chrome/Android/Cloud, and that would help in reducing they monopoly, but if there is one thing I could change it would be to decouple ranking, filtering and targeting from the rest, and open them up.
There should be multiple rankers on top of the index, users should be able to choose and create new rankers. Same for filtering - what gets hidden/censured, put the power back to the users, let them select their filter lists. Instead of one true ranking and filtering, let users customise it as they like.
