Totally valid points - but this is why oversimplifying the entire issue into "Private sector bad! Public sector good!" (or vice-versa) is a terrible idea. However, oversimplifying what big companies like Apple do as pushing ads is just as bad. Think about the supply chains involved in building an iPhone, and how the individual components are manufactured - it's decades beyond the roots in government (and remember, projects like the Internet still depended on private companies to actually build most of the hardware).
