The next generation isn't necessarily choosing, though.
Their parents are giving into their demands for *an iPhone due to social pressures entirely originated by Apple's monopolistic behavior (iMessage green bubbles).
Then, when they're locked into the Apple ecosystem from the start, it's almost impossible to break out -- even if you grow up into a mature adult that doesn't give a shit about bubble colors.
Interoperability (being able to exit an ecosystem without massive downsides, specifically) between the only two parties in a de facto duopoly is absolutely necessary and morally right, and it's a shame market failures force the judiciary to intervene. But we are where we are and there's no use putting lipstick on a pig -- the system as it stands is broken, and if left alone will feed on itself and become even more broken.
