Yeah, it seems that all Jobs did better than the rest is caring about his product rather than profits. And it seems that everybody is wondering why such a strategy could work and deliver actual profits.
Survivorship bias. Jobs himself was almost Apple's undoing multiple times because he cared more about the product than profits.
Probably why we all use Amazon but none of us love doing so. If someone else figured out delivery & pricing (Walmart is trying with Jet), we'll all slowly defect. There's no lock in.
Kindle is an adequate product that has sporadic iterative improvements and occasional backslides. Hardware is finally fine after many years of not, software is less so.
Alexa is whatever.
AWS is a cash cow, but thats more of a B2B/Enterprise offering.
That is the product and it's clear Bezos & crew obsessed on getting commerce to be as frictionless as possible & earning customer loyalty. Dealing with Amazon as a customer is still 2x better than any other online retailer in my experience.
