Though I am not a fan of Scoble I do not think that Google made Scoble and other to use the platform. Why? Two reasons:
1.) Scoble interest is to get traffic from everywhere. Raising awareness, brand recognition, etc. Google+ was skyrocketing at the beginning and for already known Internet celebs an opportunity to easily scale on another platform because at that time they were the first on Plus and quickly got traction through existing fans. And as known Internet addicts they cannot just ignore a platform. So it's a mutual and balanced relationship reach (for Scoble) vs content (for Google). Compare also other bloggers/publisher who spammed from day 1, e.g. Pete Cashmore from Mashable.
2.) There are lots of high, high level Google execs who never used Google+
Agree. Although it was embarrassing for Google in the first few days of the beta that Mark Zuckerburg had the highest number of followers on Google+, without even a single post.
