Leaving aside the tone and accepting the facts at face value, this only shows that Prabhakar was in charge when search failed at Yahoo and then at Google.

Business and technical decisions are often made by incompetent people with adverse incentives; they are sustained in their decisions and positions by larger forces and by avoiding consequences. Attacking specific (useful) idiots is less helpful than identifying how the organization evolved away from good vetting, good feedback, and incentive alignment -- the "eternal vigilance" required for the freedom to create at scale.

Please look past the heroes and villains to identify what's enabling them, particularly if you have access and care about the organization or its impacts.
