The author sounds super naive.
I'm not sure what exactly he was expecting, I believe this is how life is at all these big companies. Any of the FANGs will have the same level of bureaucracy. If you want a different lifestyle, you can join a startup or a smaller company, but this has been the way it has always been. Amazon is one of the largest tech companies in the world, I'm not sure why he would think it's somehow not a huge bureaucracy and a certain way of doing things with so many engineers.
