If I look in LinkedIn I find more job offers for Clojure than golang. For some reasons other metrics do not apply, and I guess golang is more open source related than clojure which is more about building private services.
I don't think that characterization of use is true for either Go or Clojure.
I think the reference might be more in relation to OSS tooling such as docker, kubernetes, and a lot of the other stuff in the CNCF project catalogue which is often VC backed start-ups with OSS codebases.
