Apple’s goal was not to build a phone but to build an even more personal computer; their strategy was not to add on functionality to a phone but to reduce the phone to an app; and their tactics were not to duplicate the carriers but to leverage their connection with customers to gain concessions from them.
I disagree here, this is hindsight and speculative, and the provided link is from 2013. The initial iPhone did not come with a market (the 'iTunes App Store') and AFAIK we don't know for sure if it had been planned from the beginning to pan out the way it did.
I am not trying to play down the success of the iPhone and how it has changed the world. Yes, it was incredibly successful, yes it all panned out nicely. I am just questioning if it was all planned to come out exactly this way from the beginning, or maybe there were some decisions made after initial success and someone came up with even better ideas.
