Do you have a source that it was started by Google? From looking around, they support its development but it was an industry initiative, and Samsung was one of the first OEMs to support it.

Adopted by Google yes, but since when would Google adopting a technology give them full control over the future of that technology? Surely the other industry members who started RCS also have a say?
And I would argue that the language used implies Google created RCS themselves (it was their idea): "RCS is Google's idea of a solution"
