Libertarians are disgusted by this fascist move to violate the private property of individuals.
I'm forced to agree because libertarians are moral and I am not.
It seems to me that libertarians never object to reality and real conditions, but to nomenclature. For example, if the arbiter of which opinions shall be seen is called government, even if they have no other power, then that would be wrong and it would be censorship. If, however, the arbiter of which opinions can be seen and heard is called a private business, then it's fine.
If Facebook owned all the land in the world, it wouldn't matter how oppressive the laws they made on their land; it's their land. The rest of us are tenants and should shut up about our condition because free market and private property. If they required us all to participate in lobotomies to delete our incorrect opinions to live on their land, so be it. Private property. Free market.
Non-libertarians are less focused on nomenclature and more focused on real effects of the situation, not what the situation is called. If you can't speak out because you will lose your job and starve, so the choice is between dying and remaining silent, that is what non-libertarians see, and they won't see a difference between the system being set up to make sure you die for speaking, and being killed for speaking.
Libertarians see a difference, and always check to make sure the master happens to be called government before declaring anything immoral. This is why libertarians are morally advanced and others are pigs.
I wonder what would happen if the US government just changed its name to The US Inc, and all the senators and whatnots wore sashes that said, "employee of a private business, we just own all the land."
