You might be surprised just how much a figurehead is credited in contribution, regardless of how much or little they did along the process. I imagine a significant portion of the population at large would assume Bezos masterminded and pushed most the process down to about 1-2 levels of organizational hierarchy from such headlines and glances.
The reality is, he put a business need in place (focus on metrics and quantification) and let C levels percolate the concepts around the organization until a strategy emerged. He may have signed off on it but likely someone below him did and ran with it. I'm not sure emergent organizational successes should be credited to whomever set a few initial conditions unless the entire process can be outlined into how those successes emerged and were shaped--but of course they are frequently credited to someone who simply got lucky or had piles of money to throw at a problem with the right people in the room.
While it's sometimes good someone decided to throw piles of money at a given problem, their goal was not inherently to solve the problem. It also doesn't mean they solved the problem. Lots of people throw lots of money at very important problems and get no credit or sometimes have no success.
