that would be better, but google would still be subject to attacks by adversaries and (secret) subpeonas by governments.
much better would be if they did their analytics on user data in real-time and store only the results while discarding the source data right away.
IMHO this'll end up being one of the most influential research developments of the last few years, but it's only a couple years old at this point and needs a lot of supporting infrastructure (which'll have to be done by people outside of Google - the mothership has no economic incentive to support this) before it really works well.
