I think you're right. My suspicion is that if FB/TWTR go totally ban-happy, the social discussion will evolve into a legal one and move towards overt regulation a la utilities. EDIT: IANAL, but if these platforms start favoring one political group over others, it seems potentially illegal, as it could be considered in-kind political donations.
