Out of those three, I only use Google. I still consider the 'net - and I do mean the internet, not 'the web' as that is but a part of the constellation - to be a useful resource with near-unlimited potential. I shun Facebook like the plague and Amazon is not on my radar in any way, due in part to the fact that I'm not in north-America while Amazon is still mostly targeted at that part of the world. As such any thought of these three having fundamentally transformed the web falls flat for me as they just simply failed to do so in my world. I don't deny that these companies - especially Facebook - have an unhealthy amount of influence over many people's outlook on the world around them and that they have the potential to cause great damage - again pointing at Facebook as the main risk factor due to their rather obvious lack of political neutrality - but for now I just see them as big companies intent on carving out as much of the web as they can.
