What GP meant is that the CTO of a $1b company wold absolutely not fire someone for going Azure because at those scale it's very likely they have a set of customers that exclusively want to work on Azure, so that choice makes sense.

It's easy to do blanket statements like "never choose azure", "avoid GCP at all cost" or "never again on AWS". Until real world comes your way and you are forced to deal with it.

That being said: I'd fire anyone choosing to deploy a workload on GCP.
