Most people do care about privacy, but generally they are not even aware of how their privacy is being violated - Google and Facebook are very good at hiding the reality of these things.

But you're right, the cost is the ultimate factor for most people, especially in developing countries. I guess Apple doesn't care about complete market share, but if they did, they could just release an "iPhone Lite" for 150$ and good bye to Android market share. Imagine having 90%+ mobile phone market share - Apple could destroy the Google ad business.
