Nuker was basically apologizing for the poor phrasing in his parent comment; smoldesu understandably used the same phrasing in his correction to make his point, but, in doing so, his correction suffered from the poor phrasing too. The subjects of the sentences were "half/all of mobile users", which, in the latter case for example, implies that everyone uses iOS. Nuker's intention was to refer to "iOS mobile users" only, not mobile users in general. Kudos to him for rereading his original and going "Oops! :)".
