At least from the outside TK seems to be doing well given GCP's growth. My completely uninformed assessment is that he stepped in as the disciplined adult in the room to override Google's otherwise lackadaisical approach to enterprise. (Clearly still some ways to go, as this incident shows.) Now, that may have created a culture that is at odds with the rest of Google, but it was probably required to become a "serious" enterprise org.

That said, did OCI, being an Oracle division, have a culture worth destroying? On the other hand, I could see TK importing that culture into Google...
