That’s one of the things that I think about when someone says to me that Google is evil. It’s not, at all, simply because the kind of people who I’ve met who work there have mostly been anything but evil. They’ve also been incredibly switched on to the compromises that you have to make in running a service which lives or dies by the results of advertising, and that depends on harvesting as much of the world’s data as possible.
The issue I have with Google is simply fear: not that the current crop of Googlers might do bad things with all the power we’re handing over to them, but that in the future some other Googlers will. If there’s one thing history proves, it’s that the more you centralise power, the more likely that power is to be misused in the future.
Something to keep in mind.
