Why I’m done with Chrome – A Few Thoughts on Cryptographic Engineering:

A few weeks ago Google shipped an update to Chrome that fundamentally changes the sign-in experience. From now on, every time you log into a Google property (for example, Gmail), Chrome will automatically sign the browser into your Google account for you. It’ll do this without asking, or even explicitly notifying you. (However, and this is important: Google developers claim this will not actually start synchronizing your data to Google — yet. See further below.)

and

…after I tweeted about my concerns, I received a DM on Sunday from two different Chrome developers, each telling me the good news: Google is updating their privacy policy to reflect the new operation of Chrome. I think that’s, um, good news. But I also can’t help but note that updating a privacy policy on a weekend is an awful lot of trouble to go to for a change that… apparently doesn’t even solve a problem for signed-out users.

This behavior is wrong but what do you expect from the 2nd largest advertising company in the world? The update to their privacy policy that basically no one reads is not an acceptable response.
