You're taking the perspective from places where iPhones are in a majority, or a plurality of people's pockets. In Asia, Africa, Middle East, South America etc, Android has a much larger share of the market, even if it is spread across large numbers of models and manufacturers. Apple's "stranglehold" is about as strong as it's "stranglehold" on the desktop/laptop market with Macs.
