Well the obvious example is conflict of interest cases. Take the hypothetical situation where someone writes a negative exposé on Facebook privacy policies and then plugs a competitor. Suppose in this contrived example that Facebook systematically removes all related content to this exposé and bans the creator. On one hand Facebook is a private company. On the other they are built around a communication platform and communication is a constitutionally protect right in America. Moreover, this type of practice could be considered anti-competitive and subject to anti-trust regulation (a bit unusual, but there is precedent). I am not trying to advocate one or another view on this issue...more of trying to frame what I think is an interesting question: Where is the line where private rights give way to public rights...if at all?
