I'd assume that "capitalism" is meant to refer to Android, with its open competition among as many vendors as want to build hardware that can support the OS, while "communism" refers to iOS, whose ecosystem is by comparison strictly defined and controlled from the Supreme Soviet in Cupertino.
I don't think the comparison works, though, both because smartphone users are free to choose whether or not to participate in Apple's ecosystem, and because Apple's incentives are aligned with the desires of its current and potential customers in ways that those of communist regimes historically have not been.
An alternative perspective, only vaguely serious... "All Androids are Equal, but some are more Equal than others". [1] Android is open and free, and in theory, everyone cooperates, but in reality its just a cess pit of corruption. "Free" means "free to log your keypresses", "free to kill your battery" etc. And as with all good communist wonderlands, someone (Samsung) resents the ideals and is turning the place into a dictatorship. Whereas Capitalism is nothing without regulation (at minimum a police force). The iOS market is where commerce happens.
