Not just controversial but wrong, for the most part. For example, Facebook is not a substitute for face-to-face social interaction, but complements it. (How am I going to interact face-to-face with someone far away?) The same is true for #3, #4 and the second #5 at least. Of course, if I were to spend 100% of my time on Facebook and therefore completely neglect face-to-face social contacts (<cough>), then that would likely be a problem. The opposite (100% face-to-face contacts and no online ones) would arguably be a problem too, in this day and age.
