I'm also becoming frustrated with Google's evolution toward walled gardens, an end to privacy, and away from the open (and anonymous, when needed) web. Reader to Google+ is one indicator. CISPA is another. I consider Firefox a good foil against that evolution, and I've started switching back to Firefox for my primary browser. In time, Google will have less control over my online life, because the trust I once had toward Google is fading.
I don't believe Google really believes in "Don't Be Evil", anymore, and so I have to protect myself, and push back against Google's dominance. However small my efforts may be to GOOG's bottom line. (And I still hold GOOG stock. Ethically, I'm not sure where I stand on that.)
