@jj I think many have been using that fact (that private companies can do whatever they want) as an argument for slapping heavier regulation on Facebook and Twitter due to their sheer size, and the role they have started to play in public (political) discourse in many countries. In my country, all MPs basically make all their political statements and debates exclusively on Facebook, further blurrying the line between 'Oh it is just a private company' and 'This is protected speech'
