The reason is that I greatly resent their 24/7 snooping of our private lives, especially the granularity of their snooping. For example, they know whether you need a blue shirt or a white shirt, because you clicked on a website selling such items, and Google then sells that information to advertisers selling shirts.
However, with the recent discovery of NSA spying on Americans, Google’s spying does seem a little more trivial. In addition, I see that Google is now donating $250 thousand to put a holiday wreath on all 120 thousand gravestones in Arlington National Cemetery, which is a truly noble gesture.
I know, I know, even Al Capone supported an orphanage in Chicago, but I have a weak spot for veterans. From now on, I will just deplore Google!
