Anything that can be used can also be abused (Eric Partridge). The 'use'r determines which it should be. The smartphone has a significant utility value, but monetization of such value still escapes the purveyors of such technologies. Social media is the best and worst 'ab'use of such a device.
One example for consideration is e911. Most location-based services are an offshoot of such a mandate. Can such location services be abused? Absolutely. One vendor clearly articulates the delineation, and many others have followed suit to various degrees.
Medicinal use of Marijuana vs recreational use also shows us the same dichotomy.
As a parent of two young men, my primary goal for providing smartphones to them, as they live away from me was to keep the fabric of a family together and provide some sense of security. They were explicitly asked to provide permission to track their location, with instructions on how to turn it off, in case they did not feel comfortable under certain circumstances, no questions asked. The pros/cons of social media were explained. We have some interesting discussions on such topics.
To a very large extent, CS also provides some of the same sense of family and community. The predominant access that I have is via a smartphone, albeit sporadic, due to work commitments.
