Imagine any leader that is not sundar trying to get this person fired. At some point, that leader would need to justify to either their leader, or a similarly leveled peer why they budgeted x SWE-years(where x is probably > 25) for a project that took this person far less than 1 SWE-year.
There are truths to both sides of the argument.
