The word "Evil" in Google's motto doesn't refer to puppy-kicking or kitten-drowning or armed robbery. It was a reaction to the typical bad behavior of corporations trying to squeeze another couple of points out of their profit margins in customer-hostile ways; to monopolies throwing that monopoly power around; to companies bundling crapware with their goods. Things like that.

Requiring a Google+ account probably still doesn't rise to those levels, but it's a lot closer.
