I'd be interested to hear people's proposals for where they are moving to when they leave Google, and how they think it will be any different (apart from the poorer quality service). I'm quite sure Bing or Yahoo don't store information of any sort
As for the CCTV anecdote, I personally would be delighted if Tesco analysed all their CCTV of me and moved everything I liked, and everything I might like, to beside the front door. That'd save me wading through the cr@p I know I definitely don't want just to find the things I do want, and also give me the option to go beyond "my stuff" to find new things if I so decide to.
It's also interesting to see people's varying definition of being evil. Where someone arguing it's "evil" to promote Google+ on Google
;I'd wonder if they'd call it evil if 820 Cabs had a sticker on their dashboard promoting a new service they had because they "should really have a sticker from all the cab companies in the interest of fairness". I personally would call it leveraging your service, as is normal business practice.
I also guess challenging the Chinese government and refusing to bow to government censorship of Google search results doesn't constitute an act of their "don't be evil" mantra.
