GV isn't truly independent. Best way to describe it is that multiple companies in Alphabet have access to Google's tech stack and resource manager. In the early days, I advised against GV trying to get its funded companies to GCP because it wasn't mature enough and I wanted the startups to just be successful, not be political statements about Google's cloud.
That changed over the past few years; now I would easily recommend that startups funded by GV use Google Cloud if they wanted to.
