One of the major mistakes Google made was forcing it upon users. Got an Android device you pretty much had to make a Google+ account. Then there was the whole youtube/google+ fiasco. Then Google wants you to always be logged in to Google Chrome and all it's services, sucking up every detail of you online life. So at the centre of all the Google-iness is G+, and I think a lot of people just don't want a social network attached to every other service they use.
