Are you speaking as an informed and responsible user? If so, then you disqualify. A more appropriate outlook to the situation would be to imagine Facebook as the only options that young children have. It's not just about how you use it, it's also about how it indirectly affects the people around you because of the pervasive lack of due diligence. Facebook as the only option might offer some boons, but is it worth it? I think most of us would agree that if we objectively weighed the pros and cons of the "real" Internet some solid arguments could be made that its more positive sides make up for its darker corners in spades. Could Facebook pass a similar test?

Really? What is the facebook-only internet providing on top of the sms and phone calls of feature phones that would make you pick that flood of targeted advertisements? Remember that you can't e.g. follow the shared links on your feed. And the free facebook I have used on my travels does not let you to load images.
