Apple as of years ago was capturing over 90% of all the margin in smartphones (https://www.cnbc.com/2016/11/23/apple-captures-record-91-per...). I'd argue that represents a monopoly in paid smartphones. Our option as users is either buy a phone from Apple or accept what is essentially a free service from Google (you have to buy the hardware)... who are giving that away to solidify their search monopoly. This to me doesn't represent a thriving marketplace of user choice.
