I had a hard time reading past that line since Google is literally ramming G+ down everyone's throats at every possible opportunity. It's almost impossible to use their services without being forced into a G+ account nowadays.
It's not that they're being understated, it's just that people aren't noticing because G+ is that boring to everyone.
Edit: And as I write this comment, I'm once again reminded of how idiotic the name 'Google+' is. Do I call it GPlus? G+? Google Plus? Google+? Should I put a space between them? How do you search for a plus sign? Oh, that's right... Google didn't realize they had to completely break that operator until AFTER they named their social network. How's that for a brilliant strategy?
