You can reference numerous previous discussions on HN regarding WEI for more information.
I used to work at Google, I got over the initial 'gee we're pretty nice and concerned' thing, but would like to gently point out the tendency of people to be slightly histrionic and misinformed about it. The gap between what it was, briefly, and the confidence you have in its intent and current state are quite wide. Certainly well-intentioned and appreciated, but ultimately alarmist and inaccurate.
These types of ideas with significant potential for abuse should be introduced with extreme caution and with at least majority agreement of everyone affected. Instead Google tried to pull a fast one and refused to engage criticisms in good faith. My response might seem alarmist at first glance, but I don't think that's a fair accusation given Google's behavior. I expect this proposal to return under a different name once everyone's forgotten about it and I hope the backlash then will be as severe as it was against WEI.

Sure, but I still fail to see how it would "obliterate any remaining semblance of privacy on the web".
