The illusion of freedom and control in our modern technology (phones, apps and social media websites)
The makers of the many of the apps and probably all of the social media websites we use (Facebook, Twitter, Gmail, LinkedIn, YouTube) don't have our best interests at heart, and are designed to keep us within their environments for as long as they can, and to make sure we come back often. This shouldn't come as a surprise, when most of the business models are advertising based, and more time spent = more advertising revenue potential.
