Google's new motto: "Don't be evil, but only after trying really hard to be so, and then grudgingly accepting that perhaps your users have alternatives that they might avail themselves of, and capitulate" It's not as catchy, but perhaps a little more honest.
they saw that the most profitable info they could get was tagged pictures (in use even on their captcha service).
So they moved it out of G+, and forced everyone with an android phone to upload things for them with or without a g+ account.
that's another level of evil.
