Google presents itself as an unbiased search engine.
Oh yea? Google presents their name, a text box, and a button. If you manage to find the "about" link at the bottom, all it basically says is "Google’s mission is to organize the world’s information and make it universally accessible and useful." Nothing about bias. If Google's services are better than the competitions, placing them first actually would make the results more useful and would make their services more accessible.
The concept of "fair competition" is truly lost in this day and age. How is it fair to force Google to not place their own services ahead of other results? It's their search engine. They built it. Why should some third party be able to force them to place other results first? At most, I could see maybe requiring them to disclose why some results were promoted, like what is done with sponsored links.
It's the consumers that have the power of choice here. There are alternative search engines. Some popular for the very fact that they're not Google. The fact that people are too lazy to use them doesn't mean that what Google is doing is wrong.
