Sounds nice, but for all we know, there was a govt. goon standing next to you with a gun pointed at your head when you wrote that. Or a government bureaucrat threatening to withdraw a multi-million dollar government contract. For that matter, we don't even know that it was Larry Page who wrote this.
In short, I am not willing to accept this at face value. I believe Google most likely are part of PRISM, along with MS, Yahoo and all the others.
