Absolutely correct. For the other ~99% of humanity, acquiring access to these digital tools has been a massive leap forward in all regards. Whether you were stuck in a small town in Oklahoma, born into a family in Bangalore earning $20 per month, or millions of scenarios around the globe that are in-between. McNamee seems to have no idea how the rest of humanity actually lives and what access to Internet-based information, messaging or media has made possible in terms of dramatic life improvement.
Even for 1%ers, there are people mature enough to enjoy the benefits of these services without falling prey to abusing them. You can abuse anything that feels good: TV, junk food, tabloids, etc etc.
To equate a susceptibility to addiction with immaturity is a severe error which will prevent you from ever dealing with addiction, in yourself or others, in a rational and realistic fashion. It is not about moral character, or immaturity, or lack of Godliness. It is a disease process with roots in biology and genetics.
Also, everyone is susceptible to manipulation of their dopamine reward system, no matter how robust. The impact of effect varies from person to person.
