I was asking for a source so I could look further into this, do you have any?

Neither me nor GP said that it was started by Google. Just that it was adopted by them as a solution.

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"
