Re: @AC "have to live in a box"
That's why I'd never use Google's DNS. I'd choose to use one from Microsoft, Amazon, maybe even Facebook, before I'd use Google because they have less personal information about me and it is easier to avoid them being able to correlate my DNS lookups with other personal information they collect on me.
If you really believe that, good luck to you!
I don't believe that any of those companies would hesitate for an instant before gathering, correlating, and monetizing every bit of information about you that they can get their hands on -- indeed, they'd be mad not to, considering that the others do it and it's apparently not illegal.
At least Google gives me free stuff that is occasionally useful, and for that I forgive them -- just a little -- for ravaging my privacy. The others can go swing.
