It's a pity, really. By all accounts, Google+ was competently executed, arguably an improvement over the house of Zuckerberg; but the monomaniacal push to get everyone who so much as looked at a Google service turned into an allegedly-active Google+ statistic soured everything it touched as well as poisoning the Google+ brand pretty thoroughly.
(Of note, even institutional Google Apps customers, the ones who shell out for centralized management and a connection to their preferred domain and so on, got the hard sell. And, the maze of refusal boxes and prechecked defaults and petulant nagging was like something out of the bad old days of dodgy application installers that "offered" you 6 different flavors of adware before getting to the point.)
Let it be a lesson on the limits of exploiting one property to push another, hopefully a painful one.
