I feel like that's like working at Microsoft and having never heard of Alex Kipman. The creators of Kubernetes are very open about it being based around Borg's structure. That's no secret.
I don't necessarily think you're wrong; I just think your argument, as stated, is weak.
If that was remotely true then what product/service does Microsoft offer that is remotely comparable with Docker/Kubernetes and is neither Docker or Kubernetes?
Now, I happen to think Kubernetes is better, but you asked. Service Fabric was available to the public in 2016 but has been used internally since 2011.
Because you lead nothing if all you do is reuse the tools developed by the actual leaders. That's what followers do, not leaders.
