I don't mind Google knowing stuff about me ... as long as they use it in a limited way .. to find companies, products, news etc... in which I might be interested. I don't particularly want foreign governments to know the same stuff - because they have a tendency to use that information for entirely different purposes ... namely, to try to put me out of a job.
