His flash example is particularly bad because it's not a setting that should be binary in the first place. Auto/On/Off are all important settings for flash photography. Removing one of them would actively anger a lot of people. This section is actually a really great example of how tiny decisions made in UI can actively reduce usability even though on the superficial level it seems like a good idea. I also think flash mode is represented well on most camera apps. I wouldn't change a thing about them other than maybe adding a text label.
