I noticed this blog: thenextweb.com: Google Blocking Negative Search Recommendations On Islam – Why? today (a bit late possible).
It tells about how Google possible is censoring search suggestions which could be controversial - in this case towards Islam.

Most everybody knows about Google in China so we know Google does … lets call it fiddle to be neutral ... with the search results in various situations.
However this begs the question - how do we actually know that Google is acting fairly and doesn’t censor or cheat with the search results in ways we cannot know?

Their revenue comes from advertisement and being able to provide a clear picture of what people search for to provide targeted advertisement.
So it would stand to argue that they can’t really afford to suffer doubt about their objectivity and whether or not they alter or effect or even censor search results.
However how would anybody know?

Is Google now so big that it doesn’t matter if they do questionable things? Can … would … people even stop using Google if it was confirmed that they are actively censoring? Is it even possible? Or are Google now so big that they can do what they want, when they want?

One can only speculate but my trust in Google is diminishing as they keep growing bigger and spand more and more features of the web, and with situations like this and China.
I still use their services, however …for now.

Do no evil.
