Yeah, "customer obsession" really just means "market share / growth obsession" which is a means to (eventually) making monopoly profits. Which Amazon seems to have achieved.
All the amazon corporate values are derived from making profit. Two-pizza teams? More like "three slices isn't frugal", one or two should be enough for you.
You can also “coast upwards” for quite awhile - as an example we now pay Microsoft less than we were for periodic upgrades to Office for the entire Microsoft 365 suite (including email hosting, etc) but all the machines are now Macs. They make more from us in one way, but less in total dollars.
