(Yes, my question indicates a very slight amount of bias!)
I used to do consulting for a company (LocatePLUS) that bought databases from different sources and then linked them. They sold this as a service to law enforcement and private investigators on a per query basis.
Also, unrelated to your reply but... while I understand how people might personally like Google (or Apple, or MS, or whatever), but business is just business, shouldn't be a religion or a sport. People should see beyond the "I like that company".
I definitely see Google as a business and know that circumstances can change with a change in management or operating environment; there is no way around that though. In my opinion we can either fight big companies and hope to have the government or other large companies keep them in check or we can try to help shape the environment and support companies that further our best interests.
