Of course people don't care more about iPhones than their own kids. Pick just about any X and people don't care more about X than their own kids.
That doesn't mean X doesn't matter, or people wouldn't care more about it if the understood it better, or wouldn't be better off if it was different, or that we shouldn't try to do something about it.
And if you're talking about a poll where you ask people whether they would like to have a larger selection of apps for their phone, or they think it should be easier for small developers to enter the market, or they think Google should have more control over their phone than they do, the majority of people are not going to choose less apps and less freedom at the same price.
The fact that you have to put it against dollars to get them to do what you want is just leveraging the fact that the median user is not rich to claim that nobody wants something that everybody wants because everybody also wants to save money (and the implication that the median person values it at less than a penny is hyperbole). Why should you have to pay extra for freedom? Should only the rich have it?
