The graph in itself is pretty close to privacy issues that border closely as well. Even if FB et al were government funded that wouldn’t make it good either. And said data could be considered competitive advantages but perhaps not. If everyone got a copy of various social networks’ friends lists, the number of viable alternatives would skyrocket quickly because the lock-in effect would be gone. Perhaps this needs to be theorized more along modernized anti-trust laws (which don’t work in a tech given anti-trust laws were based around trying to lower consumer prices).
