For my part, I share many of the frustrations voiced here. I can't stand Google's persistence in ensuring I'm constantly logged in, or Chrome's ever helpful reminder that I should sync it with my Google account.
The business case is obvious, but it doesn't mean I have to like it. In fact, I dislike it enough to no longer use Chrome as my default browser and have moved away from all of their services with the exception of Gmail.
I don't take my privacy as seriously as some here, but it's easily gotten to the point that I no longer feel comfortable trusting Google with the entirety of my online experience. For what it's worth, my bar [for not-trusting-companies] is set relatively high, and Google has absolutely begun clearing it, unfortunately.
