One reason for which I don't like Google anymore is that they broke their primary promise, which they were emphasizing more and more around 2004-2005 (if I remember correctly): to make most of the world's information easily accessible and shareable, and, why not?, trying to make a difference in this world.

In my ideal world the Wikileaks info would have lived in a Google sub-domain, climate change discussions would have been based on open charts and data which would have been also hosted by Google (with available info going back since the first meteorological observations were made), mashups about Iraq and Afghanistan wars with geo-located user-uploaded photos could have lived at maps.google.com/war and so on and so on.

I know that what I was dreaming about doesn't add any stock-market value or anything (and in the worst case scenario it gets you straight into jail), but that's at least what I call "changing the world, trying to make it a better place", like guys such as Diderot or d'Alembert did three centuries ago.
