Do you have any idea how evil that sounds? If that is the argument, this is my answer: I will take up arms and die fighting to prevent the realization of such a goal.
Media ownership limits are justified only because of a resource scarcity. They do not apply to Internet publications, and with search engines, all I have to do is type in a different domain name. There's no spectrum to be monopolized.
Media ownership limits are about market monopolies, not scarcity, newspapers being a prime example.
If it undermines a country's judiciary for information about crimes to be published, that country's judiciary needs to be undermined. Once information has leaked beyond law enforcement officials, there is not and should not be anything anyone can do to prevent its spread.
I don't care what mission Google is on. Rights are not dependent on motive.
Newspaper ownership limits exist only in relation to broadcast station ownership. There are no separate limits on newspaper ownership.
I think a comment[1] I wrote a couple months ago about Facebook is relevant here.
Infrastructure is what services are built on. It's a prerequisite, not the end result, and its absence is extremely costly.
Google is not infrastructure[2]. Like Facebook, it could disappear tomorrow, and we'd all just switch to other search engines. I assume Bing would immediately pick up most of the users, either directly or via Yahoo. I wouldn't like it as much, but I would not be materially harmed.
Google has done nothing to make it harder for someone else to build a search engine except raise the bar for quality. It has a better product for most people, so it has the most users. That's how it's supposed to work.
Using Google's popularity as an excuse for regulation is nothing but a demand for mediocrity. It's saying good things aren't allowed to exist, and that people shouldn't have the right to choose (or make) better products.
It's saying "CONFORM!".

[2] Well, Google does offer something closer to actual infrastructure of course, in the form of their App Engine/Compute Engine offerings, but they're even less dominant in that field.
