When discussing the bad impacts of things like these, It's important to remember that we are under no impression that it is bad for everyone. But it is bad for SOME people. And that is enough. Some people will have their life ruined because of exploitative companies. Because their model promote unhealthy behavior that will consume their lives. Everyone knows that this is true. Some people out there are consuming too much time on facebook and having their live ruined as consequence. Just because it's not "everyone", or even a big percentage of the user, doesn't mean that we should be indifferent.
