Without really no knowledge of the Google ruling in my opinion it seems that it's a flick to show Google that there is a line that it can't cross. Maybe Google in all of its superiority has become too arrogant, who knows.
And free markets work only if they are fairly regulated. If there was no penalty from abusing your monopoly you think companies wouldn't do it? I think even Google wouldn't be all the goody-goody with its business practices if we'd let its actions go unchecked. Granted Google seems better than most.
Unless they result in a monopoly, which has arguably happened in the case of Google. Users only want to use one place to search, Google is currently dominant and the problem seems solved well enough that no newcomers are likely to succeed in the future.
Now Google is using its monopoly on search to move into a new segment (shopping) with an unfair advantage.
How are the markets (spheres of influence) of USA, EU, and China different?
What makes one of these markets more free than the others?
And I am not a fan of the EU's approach to regulation, economically they are already failing and I predict that it only gets worse.
Free markets win every time.
