I think the main issue is that he's singling out the iPhone as if it, outside of any other smartphone, is somehow more difficult to use than any other ultra-complex piece of technology and then proceeds to demonstrate that, poorly IMO, by pointing out several edge cases that the majority of users will never experience. His first example, case in point, is that users are never asked about text size when that's demonstrably not true. New iPhone users are presented with that during on-boarding and existing users have already made that choice. Changing it is in the settings. It's not Apple's or Samsung's or Nokia's fault if someone has another person set up their device for them and choose their preferences. The WiFi example is another one. The entire premise of those features is that users prove that they're capable of navigating to the manual selection of that feature because they need to do that at least once in order to turn the auto-discovery off. That's very intentional.
